Different Types Of Steel

Stainless steel has innumerable variations that can be used, from creating custom wire to making a basket, tray and eating utensils. It can be divided into ferritic, austenitic, martensitic and duplex. Remember, though, the best steel for you will depend on the application it’s intended for. Each type of stainless-steel alloy has its unique properties that allow for strength, oxidation resistance, corrosion resistance and melting point. For piping, stainless steel pipe suppliers would be able to help you understand the difference and which one will be suitable for your project. To help you get a better grip on the differences, we have compiled a list that explains everything to you.

Ferritic

This type of steel is based on chromium, with small amounts of carbon, less than a percentage. They have a similar microstructure to carbon and low alloy steel and are usually limited in use to moderately thin sections because they are not tough enough to handle the heat and power of welding. When welding is not required, they offer a wide range of applications as they cannot harden under the pressure of heat treatment. Such steel is also selected because of its resistance to corrosion cracking caused by stress, and they are not as formable as Austenitic stainless steels are.

Austenitic

This type of steel is one of the most common and its microstructure is a derivative from the combination of nitrogen, nickel and manganese. It has the same structure that you will find in ordinary steel but at higher temperatures. Such an arrangement that gives this steel its distinguishing characteristic combination of being accessible to weld and change forms. It cannot be hardened by being put under the pressure of heat treatment but has the useful property of being able to be tightened to high strength levels. This can be accomplished while still retaining the level of its flexibility and strength.

Martensitic

This type of steel is similar to ferritic steels in structure because it is based on chromium. However, it has higher carbon levels, and this allows them to be hardened and tempered like carbon and low-alloy steels. Such steel is used where increased strength and toughness, as well as moderate corrosion resistance, is a requirement. This type of steel is difficult to weld and change its form, making it common in long-sized products rather than in sheets and plate form.

Duplex

It is a type of steel that has a microstructure which is about 50% ferritic, and the rest is austenitic steel. Because of this, Duplex steel has a higher strength than both austenitic and ferritic steel. Such power makes it resistant to cracking caused by corrosion. There is what is called lean duplex steel which has corrosion resistance comparable to austenitic steel but with enhanced strength, while super duplex steel not only has the same characteristics but also more comfortable to weld and have reasonable formability.

Getting to know and understand the different types of steel is not only valuable knowledge to have but also great for when you need a specific kind of steel for a project. You will appreciate the difference in strength and what will work for you.
