Now, we are putting some key facts related to stainless steel for you-

  1. Stainless Steel Can Stain

While we think of them as stainless, they can stain.

It creates a thin oxide film when exposed to oxygen, and can regain its original form.

Permanent damage will take too much time, and the oxidizing has to be too hard.

  1. Stainless Steel As Soap

There are ‘soaps’ crated using stainless steel which doesn’t work the regular soap but kills strong odors of onion, fish, and garlic from the hands.

  1. Stainless Steel Is Recyclable

As per the studies from the American Iron and Steel Institute, about 88% of the world’s total steel is recycled.

  1. Stainless Steel As Having Magnetic Properties

While most stainless steel elements are non-magnetic, one specific type i.e.

martensitic stainless steel is ferromagnetic can exhibit permanent magnetic properties.

  1. Stainless Steel In Multiple Forms

It can be drawn into a thin, or it can be turned into a wearable steel mesh, without losing the toughness and other properties.

It’s the versatility that stainless steel offers that specific stainless steel wires are used in clothing, for decoration or support.

  1. Stainless Steel Corrodes

Send an electrical pulse through a stainless steel wire, and you will notice it turning yellow and blue, a sign of oxidation.

  1. It Is Everywhere

From kitchen appliances to living room décor item to an accessible building made from stainless steel, you will find this metal everywhere.

Selecting the Right Grade of Stainless Steel

Stainless steel is among the best corrosion resistance material out there. But that is not merely it; stainless steel has a lot of benefits including excellent formability, high strength-to-weight ratio, low maintenance, ability to recycle, etc. Owing to its versatility, stainless steel has a wide range of application. Stainless steel comes in a lot of different grades, and we will help you pick out the best for the job.

  1. Formability

If the application needs stainless steel with good formability, try not to use the martensitic category of stainless steel. Instead, you should opt for the austenitic grade (304 or ferritic grade (430) of stainless steel. Moreover, Martensitic stainless steel can get brittle and lacks adequate formability.

  1. For Welding

Welding stainless steel is completely different from welding carbon steel as there are high chances of hot stress corrosion cracking, intergranular corrosion, etc. Austenitic group of stainless steel are among the most welded stainless steel. If you are welding, then it is recommended that you use 304L or 347 grade of austenitic stainless steel. While the grade 304L features lower carbon, 347 comes with niobium stabilizers, assisting in the protection of intergranular corrosion. You can also use ferritic stainless steel grade, including 439 or 439.

  1. For Machinery

If your process requires stainless steel to be a machine, you have to be more specific about the grade of stainless steel you choose. While a majority of stainless steel can be machined, some are more complex than the others. You need to optimize the machining process to boost the efficiency of your work, along with using the right tool. Sulfur can be added to improve the machinability, which you can find in grade 303 stainless steel. Additionally grade 416 stainless steel tube is another good example of it.

  1. The level of Corrosion Resistance

Stainless steel is known for its corrosion resistance properties. However, different grade of stainless steel offers a distinctive level of corrosion resistance. If you need maximum corrosion resistance, then you should opt for austenitic stainless steel as they contain the highest amount chromium. So you should opt for 304 grade of stainless steel. Ferritic stainless steel, on the other hand, is a more cost-efficient option than austenitic stainless steel as they have less concentration of nickel and chromium.

  1. Heat Treatment

If the stainless steel is going through any heat treatment, you should be aware of how different grades might be affected by it. For austenitic and ferritic stainless steel are two non-hardenable grade of stainless steel when exposed to heat. Martensitic or precipitation hardened stainless steel is ideal for heat treatment.

  1. Strength Requirement

Martensitic stainless steel grade such as 440C or precipitation hardened stainless steel grade 15-5 PH 17-4 PH are the best options when it comes to acquiring maximum strength. Considering the high nickel content, austenitic stainless steel also offers high toughness and ductility.

The right grade of stainless steel depends on the purpose you need it for. Above are some of the best choices for the grade based on unique purposes, so next time you will be able to make the right decision.

Everything You Need to Know About Nickel Alloy

Nickel is a chemical element, which is represented by Ni symbol and an atomic number of 28. It is a silver-white lustrous metal featuring a tinge of gold hue. It comes under the transition metals and is extremely hard as well as ductile.

Nickel is a versatile metal and tends to alloy with a majority of metals. Nickel alloys are alloys wherein the nickel stand as the primary element. There is a complete solubility between nickel and copper.

The high versatility of this material accompanied by its exceptional corrosion and heat resistance makes it an ideal material to use in many industrial applications.

Types of Nickel Alloy

Nickel can be easily alloyed with a majority of metals, including chromium, copper, molybdenum, iron, etc. Moreover, when nickel is added to other metal, the properties tend to alter. Below we are mentioning some common types of alloy –

  1. Nickel-Copper Alloys

Nickel-copper alloys are extremely resistant to corrosion by seawater and saltwater; thereby making with ideal for marine applications. This type of alloy has 63% nickel and 28-34% copper concentration.

  1. Nickel-Iron Alloys

Nickel-iron alloys are ideal for application where the thermal expansion in the property is at a low rate. It has a high degree of dimensional stability, making nickel-iron alloys quite useful in building applications such as thermostat rods, measurement equipment. Some nickel-iron alloys that hold a higher concentration of nickel are used in the manufacturing of transformers, memory storage device, inductors, etc.

  1. Nickel-Chromium Alloys

Nickel chromium-alloys are reckoned for their high resistance to corrosion, greater electrical resistance, and high-temperature strength. This type of alloy is used in making heating elements like toasters.
