What is austenitic stainless steel?

Lid sinds 18 nov 2020

Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. specializes in the development and production of high-quality austenitic stainless steel seamless pipe and nickel-nickel alloys. Here is an introduction to austenitic stainless steel.

Austenitic stainless steel refers to stainless steel with an austenitic structure at room temperature. When the steel contains about 18% Cr, 8% 6-10% Ni, and about 0.1% C, it has a stable austenite structure. The austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and the high-C-Ni series steel developed by adding Cr and Ni content and adding Mo. Cu, Si, Nb, π and other elements on this basis. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low. It is impossible to strengthen it through phase transformation. It can only be strengthened by cold working. For example, adding s, Ca, Se, T white e and other elements, it has Good machinability.

In addition to resistance to oxidizing acid medium corrosion, this type of steel can also be resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu. If the carbon content of this type of steel is less than 0.03% or contains Ni, its resistance to intergranular corrosion can be significantly improved. High silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid. As austenitic stainless steel has comprehensive and good comprehensive properties, it has been widely used in various industries.
