7 Essential Facts You Should Know About Alloy Steel

Alloy Steel

Alloy steel is a type of steel which contains different elements like nickel, silicon, copper and manganese. Elements like nickel, copper, cobalt and copper help to increase the temperature range between which austenite exists. Minor metals such as titanium and zirconium create carbides that increase the strength and hardness of steel. Silicon, molybdenum and aluminum extracts can decrease the effect of solubility of carbon. Cobalt, nickel and silicon can reduce the carbide stability of steel. This causes breakdown and creation of new graphite. Continue reading “7 Essential Facts You Should Know About Alloy Steel”

5 Common Applications for Stainless Steel Tubes

A variety of industries depend on stainless steel tube for different applications. Its versatility makes it the best choice for different applications. With the application of nickel, molybdenum, and chromium in various amounts, manufacturers come up with different grades to suit different purposes.

The use of stainless steel tube in the different industries is mainly supported by the fact that it is low maintenance and doesn’t affect the metals and other materials it comes in contact with. Let us take a look at the most common applications for these pipes.

High-Pressure Applications

In factories where liquids are pumped through at high pressure, stainless steel is the best material to use. The grade may vary depending on the pressure that will be passed through the pipes. Some of these may be welded together while others are seamless and there are some grades that can handle high temperatures combined with high pressure.

Aviation Application

Different parts of an aircraft will utilize stainless steel. The engine probably uses the most steel, especially where high temperatures will be experienced. The kind of steel used usually has a composition of chromium and nickel. Aircraft engineers prefer lighter steel which is also strong. 304 is a common grade used for tubing and wiring. The jet engine utilizes 321 grade because of its high resistance to temperatures that reach 1500°F. it is also used for the exhaust ducts. Other grades commonly used are 316 and 430.

Food Processing

In industries that deal with food as well as pharmaceuticals, stainless steel tubes are used because they do not contaminate the food. Nothing in the steel will sip into the food so it will remain safe and clean. Any process that needs to maintain the purity of the substance that washes through the pipes can use stainless steel. 304 grade is a common food grade steel that is used for this purpose. However, sometimes it has to be substituted for a more corrosion-resistant grade like 316 which can even withstand acidic chemicals and heat without getting corroded.


The mining process uses a lot of pipes. In most cases, these pipes need to be corrosion resistant as well as withstand high pressure. Stainless steel pipes meet those criteria and that is why they are used. For offshore mining, alloys that contain molybdenum can provide good piping without getting affected by the salty water. Sometimes the pipes through which the oil is transported need to be heated to keep the crude oil in liquid state, this requires pipes that can withstand repeated exposure to heat.

Decorative Application

In construction, stainless steel pipes provide decorative railing because of their shiny nature. Various grades have this property and at times it depends on what one is ready to pay to have a particular grade. At the same time though, they need to consider where the pipes will be placed. Some places may expose the pipes to a higher degree of corrosion.

There are many more applications for stainless steel pipes, but these 5 are the most common. Sometimes, a special grade of steel can be made for special projects. You would need to ask the manufacturer about having that done.

Quick Guide: All You Need to Know about 304 Grade (The Most Popular Alloy)

When you talk of popular stainless-steel grades, 304 is one of the first that comes to mind for most buyers. This is not surprising though considering the quality that comes at a fairly cheaper price in comparison to other austenitic grades. Although there are other cheaper ferritic grades, 304 has more applications for many.

For some of our clients who may want to reduce spending on alloys, we would recommend the ferritic grade. Although it brings down the cost, there is the issue of rusting that will occur if the metal is not painted. This is why Arch City Steel usually recommends 304 which many clients have come to appreciate for its performance.

Even though 304 was created more than a century ago, it continues to outcompete the newer grades when it comes to popularity. You will find more engineers know about this grade than they do about some of the improved grades.

It is probably something beyond price that attracts many to it. We ensure that we make the finest alloys with the right amount of elements in them. 304 stainless steel contains 18 percent chrome, this is a very important addition to the steel because it provides its most important property which is corrosion resistance. For most applications that will not involve excess exposure to corrosive environments, this steel will do the job.

304 also contains nickel which is probably what makes it more expensive than some other alloys. The nickel in this grade is 8 percent and it is not there simply to make the alloy expensive. It acts as a stabilizing element. Nickel adds ductility as well as strength to this austenitic alloy. This is a property that makes the steel applicable in a number of industrial tasks where strength is required.

With just about the right amount of nickel, this grade is fairly affordable and yet still strong enough to be used in different ways. Its workability is great as it can be welded, cut, and adjusted to suit certain applications.

Is it Always the Best?

Because of its popularity, you might be moved to believe that it is the best grade to use. Well, if what you are looking for is to use it in food-grade applications or simple construction and chemical-pharmaceutical tasks, then it will be just fine, there would be no reason to buy something more expensive for such applications.

Some other applications may require a higher level of corrosion resistance and that is when it may not be the best choice. Reputed suppliers usually encourage buyers to speak to an expert first before they determine which stainless steel grade to get. Sometimes we recommend its close substitute 306 which also contains chrome and nickel but also has molybdenum added to it for extra corrosion resistance. You would have to pay more, but if you will be using it in a highly corrosive environment, it would be the best choice.

How to Find the Right Stainless Steel Grade for your Needs

Stainless steel products share many characteristics. However, they differ when it comes to grades. Types 321 stainless steel tube, for instance, varies from 302 with the addition of titanium stabilizer. Therefore, understanding the different grades available is critical to finding a product that matches your personal and budgetary preferences.

If you are planning to buy stainless steel, you’ve probably come across the term grades. The grade is how experts categorize the production specifications, mechanical properties, and composition of stainless steel. There are over 3,500 grades of stainless steel in the market, but these grades aren’t created the same.

Of course, choosing the right grade will boil down to your needs and preferences. For example, a 321 stainless steel tube can be a great choice if you look for a product that works well in high-temperature environments. Type 321 is a standard austenitic 18/8 chromium-nickel alloy blended with titanium. The titanium stabilizes the material and removes its susceptibility to the effects of intergranular corrosion. It is resistant to sterilizing solutions, atmospheric corrosion, and different types of inorganic and organic chemicals. You can also look into other options, including ferritic steel, which is cost-effective or duplex, which offers a little bit of ferritic and austenitic stainless steels.

With that in mind, here is how to find the right stainless steel grade for your needs.

Consider strength, toughness, and ductility

As we mentioned above, your needs will dictate the type of grade you end up with. Different stainless steel grades have different strength, toughness, and ductility. Stress means the amount of stress the tube can take before it deforms or fractures. Toughness is its ability to absorb energy before it fractures. While ductility is its ability to withstand molding without it breaking or losing strength.

Think about the form and process

You will want to bend or coil your stainless steel tubing to fit into your operations in many cases. So, if your tube will go through any form of the machining process, it is a good idea to ensure that its machining rate mitigates the risk of work hardening. Otherwise, you should go for a free machining grade.

Consider the corrosion-resistant threshold

Stainless steels are known to be corrosion resistant. However, different grades have different thresholds. Stainless steels usually have 10-30% chromium, and thus, are corrosion resistant. The addition of nickel in austenitic grades offers the highest ductility and toughness among stainless grades. Grades with nickel, molybdenum, and chromium have the highest corrosion threshold.

Look at the cost

Austenitic stainless steel tubes can be expensive than other alternatives. However, when you consider their corrosion-resistant nature, along with durability, easy maintenance, and versatility, then it offers an incredible ROI compared to other options. However, if saving is at the top of your mind, you may want to look at the cost-effective options like ferritic steel. They still offer the benefits of steel but come at a lower price.


All stainless steel tubes come with an intrinsic benefit of durability, corrosion resistance, and strength. What differentiates one grade from the other is the degree of this quality, which boils down to the composition and specifications.

Choosing the Right Stainless Steel Tube Vendor

One of the most challenging problems that first-time buyers face is finding the right stainless steel tube vendor in the market. With an incredible selection to pick from, one could get easily overwhelmed or intimidated by the process.

The market has no shortage of stainless steel manufacturers, suppliers and vendors. A quick search online will reveal dozens of options near you. This can be a great thing if you think about it from an “options” perspective. However, since these vendors aren’t created equally, picking any option without consideration might mean missing out on amazing deals – or quality products.

Unfortunately, many first time buyers make this mistake, and end up learning the hard way. In this article, we will discuss some of the top qualities you should be watching out for when choosing the right stainless steel tube vendor to ensure you get the best value out of your investment.

Consider industry reputation

Stainless steel tube manufacturers aren’t created equal – some are better than others. When you are looking for the right vendor, it is important to pay a close attention to the reputation. This is how well they are known in the market, and what they are known for. A good vendor will have a great reputation for selling quality products. You can check out their online reviews along with testimonials to have a clue of what other people think about the company. You can also check out their social media platforms for the same.

Consider the stainless steel grade

When checking the grade, you’ll need to pay attention to aspects like strength, toughness and ductility, form and process, preferences and the operating environment. Strength means the strength the tube can withstand before is deforms or fractures. Ductility is the tubes ability to be bent without breaking or losing strength. Basically, these aspects indicate quality of product.


Location is another critical aspect. The internet has made it easy to buy solutions from different parts of the world. You could browse for and order stainless steel tube from American even when you are in Europe or China. But if you are concerned about the process of importing and duties that apply, or if you are only placing a small order, it might be a good idea to buy from a vendor near you. Better yet, you should find one who delivers to your country and is willing to work closely with your throughout the process.

Customer service

Find a company who values your business, and appreciates you as a client. You don’t want to be another number. That’s why you should only work with a vendor who answers your questions, addresses your concerns, and is happy to serve you. Good customer services means effective communication, proactive care, and flexibility to accommodate your needs.


Cost is usually the last thing you should worry about. Ideally, you want to check all the aspects mentioned above before you considering the cost. A reputable vendor with quality products might charge higher, but you are sure to get value for your money. The same cannot be said for all vendors.


Finding the right stainless steel tubes vendor can be easy or hard depending on what you know (or don’t know). But with these tips, you should be able to identify the right one for your needs.
