All You Need to Know About Powder Coating for Stainless Steel

316 stainless steel tube is one of the grades that you might choose to buy. Selecting the right series or grade may be such a hard task. You have to consider several factors. One of the factors you will have to look at is whether the stainless steel you are buying is powder-coated. This article briefly explains this feature:

What is Powder Coating?

One of the cost-effective methods you can use to improve the corrosion resistance of 316 stainless steel tube is coating it. Other ways that can be used to prevent corrosion include the use of corrosion-resistant alloys, which can be so expensive.

Powder coating is a term that refers to the shielding layer, which offers an irrepressible covering to materials and metals which need to be protected from corrosion and its effects.  It is a dry coating method, this means that it is firm when applied to the base of the material. This kind of coating comes in different colors, chemical composition, and thicknesses.

Application of Powder Coating

The use of a powder coating spray gun is the most popular way of powder coating. It pushes the powder coating substance at the substrate that is undergoing powder coating. The process also gives an electrostatic charge to the particles. These electrically charged particles aids in the formation of a bond.

The material or metal that has been coated is then put in a curing oven. The curing oven provides the heat that is necessary for the powder to stick together and stick to the base substance without any need for an electrical charge.

Another way of applying the powder coating to a substance is by using a fluidized bed. This process includes the heating of the base metal and then submerging it in a container that has a powder coating substance. After that, the coated material is put in a post-curing stage.

Types of Powder Coating

There are so many varieties of powder-coating that can be used. However, only two categories of powder coating materials exist. These are thermoplastics and Thermosets. The two are discussed below.

Thermoplastics

This type of powder coating material can be put to use for more than one time. This feature makes them of great benefit to removing the coat and other post-curing alterations. These types of materials are also ductile. They, therefore, have a perfect ability to withstand any impact without fracturing. Examples of these materials include polyester, chloride, and nylon.

Thermosets

This is a type of powder coating material that results in cross-links between the molecular structure when they are treated. This type of content is more permanent than thermoplastics. They are less affected by temperature after they have been cured. This feature makes them perfect for high-temperature uses.  They are also cheap and affordable than other types of coating.

Types of Metal that Can Be Powder Coated

The powder coating process is ideal for nearly all types of metals. The reason for this is because they can carry an electrostatic charge to have the material necessary in powder coating stick to them. The temperatures that are used in the curing process are also ideal for most metals.

Brief Guide: Process for Welding Nickel

So many things can happen in the process of welding a nickel tube and you need to know about it before you get nickel alloy 600 tubing.

Nickel alloy tubing consists of a wide range of elements and they can pose a critical challenge when it comes to fusing. This and other challenges can be experienced in the welding of nickel. You, therefore, have to devise a comprehensive process that can help weld nickel without problems. Here are some of the processes you need to know when you get nickel alloy 600 tubing:

Using the Metal Inert Gas in Welding

Metal inert gas welding is also referred to as gas-metal arc welding. This is one of the common processes that you can use in melting a nickel tube. The process highly resembles the welding of carbon steel process except for the shielding gas compositions. Low levels of oxygen gas and carbon IV Oxide gas should be used in the process of welding nickel. The levels should be 2% or less. You also have to incorporate tri-blend shielding gases like helium and argon to make the nickel tube resistant to corrosion. The filler wire should also be used to prevent cracking.

Welding Using the Tungsten Inert Gas

Tungsten inert gas welding is also called gas tungsten arc welding. It is also another commonly used process that you can apply in welding a nickel tube. It highly resembles the welding of carbon steel process. Nickel and carbon steel all require a direct current electrode negative. Shielding gases like argon and helium are also used in this process. Low carbon is used as a filler metal to prevent any form of corrosion.

Flux-cored Arc welding

The flux-cored process can be used in welding a nickel tube. However, this process does not give optimal results in the welding of nickel. A mixture of special gasses should be used to make the welding process more effective. Using a combination of these special gasses and a flax-cored arc is more effective than just using flux-cored arc welding, this is because the gasses help in shielding the metal that has been welded from the atmosphere.

Metal-cored Arc Welding

This is a better alternative than flux-cored welding and gas-shielded flux welding. This is because this kind of welding does not rely on flux during the welding process. The metal core is used instead. The metal core is attached to the filler. The metal is filled with powdered metal that escalates deposition, this is even though the filler has some deoxidizers.

Laser Beam Welding (LBW)

This type of welding process is useful in joining nickel quickly and low heat inputs. Porosity and cracking may be experienced in the welding process, and as such, care has to be taken to avoid such instances. You can do this by reducing the amount of oxygen. You can use a shielding gas in its place or through a weld parameter optimization.

Other Welding Processes That Can Be Used

Those processes that have been explained above are the most common welding process that can be applied in welding a nickel tube. Several other processes can be used in place of those. These include Friction Stir Welding (FSW), Shielded Metal Arc Welding (SMAW), and Plasma Arc Welding (PAW), among others.

Stainless Steel

Comparison Between Stainless Steel Types 304 and 316

Stainless Steel

Stainless steel contains low carbon and about 10 percent chromium, which makes it more resistant to corrosion and shiny on the surface. It has a wide range of applications, from the fabrication of chemical equipment, to food equipment and in architectural applications. The chromium that is added makes it possible for the metal to form a hard, adherent chromium oxide film that resists corrosion. In case the metal develops a scratch, the film will react with oxygen and self-heal. This explains why 316 stainless steel tube is used in adverse applications, and they remain functional for many years.

Both 304 and 316 stainless steel tube have a solid structure, are easy to work with, and corrosion-resistant. These properties make them suitable for outdoor landscaping and architectural uses. The main advantages of stainless steel include durability, the ability to remain attractive, and low maintenance, among others as outlined below.

  • High resistance to corrosion
  • Resistance to heat and fire
  • Hygienic to use
  • Maintains aesthetic appearance
  • It is strong but not heavy
  • Easy to fabricate
  • Resistance to impact
  • It is durable

Austenitic 304 and 316

Austenitic stainless steel is made up of either chromium and nickel or chromium and manganese. The carbon quantities are maintained at low levels of 0.08 percent as a maximum, while the chromium content is between 16 and 28 percent. Nickel, on the other hand, has to be between 3.5 and 32 percent.

These two types of stainless steel cannot be hardened by exposing them to heat, but high strength can be achieved by a process known as cold working. Compared to the other variations, they are more malleable, and they have high elasticity and high levels of strength. Because of these properties, they are used to manufacture drainage pipes, grates, floor sinks, and trench drains, among others.

Difference between Type 304 and Type 316

By observing these two types of metals physically, you will not be able to pick any differences. Their unique differences can be deduced from the chemical composition. A look at them separately will bring out their distinctive characteristics.

Type 304

This type of stainless steel is the most commonly used. It is made up of between 16 and 25 percent chromium and 36 percent nickel. It also has essential traces of carbon and manganese. The most common chemical combination is known as 18/8. This is because it contains 18 percent chromium and eight percent nickel. This amount of chromium content makes the metal more resistant to corrosion and oxidation. In its element, type 304 steel is malleable, versatile, and very durable. When used in delicate places such as in a meat processing plant, it inhibits the growth of bacteria, making it healthier.

Type 316

This steel type is also referred to as marine grade stainless steel and resembles the Type 304 in many ways. The only difference is that it contains a molybdenum content of between two and three percent. This molybdenum improves the resistance to corrosion further, making the metal suitable for use in places with salty water, hence the name marine grade. It is also used in extremely acidic environments. Coastal areas have salty particles in the air, and in such places, highly resistant metals such as Type 316 are used because they will not need to be replaced from time to time.

When thinking of pipes, have you ever faced a head-scratching moment when thinking about safety, durability, and strength? Well, there are several solutions to that. One of them is using a 321 stainless steel tube.

By itself, stainless steel is not a naturally occurring metal. It is an alloy of chromium and iron as the main element. Chromium plays a vital role in reducing corrosion.

Increasing the percentage of chromium translates to increased resistance to corrosion. Other elements that are included in the alloy are molybdenum, nickel, manganese, silicon, and carbon. It is vital noting that these elements are added in varying proportions depending on the desired end product.

Applications

Stainless steel tubes are not restricted to round shapes. They can be oval, flat, and even rectangular-shaped and It all depends on the intended use. However, it is imperative noting that tubes are usually available in varying grades such as the 321 stainless steel tube. The following are some of the applications of stainless steel tubes.

  1. The auto industry

Ever came across a rumbling car? If you have, chances are the muffler was made out of a stainless steel tube. Car mufflers are in most cases located under the vehicles, and this makes them vulnerable to the elements. Corrosion occurs when oxygen reacts with metals to form an oxide.

If wrong metal materials are used, corrosion can prove to be an expensive affair if car exhaust systems are anything to go by.

  1. Production lines

Since the invention of the production line, more products can get to the consumers within a record time. However, it is imperative having in mind that improper handling of some products during manufacturing can result in some illnesses or the goods going bad.

To write-off the possibilities of such eventualities, some safety measures must be met. Milk, water, soft drinks, alcoholic beverages, and other liquids need handling with maximum safety in mind. And one of the best ways of achieving that is by using stainless steel tubes when transferring fluids between vessels.
