The Cr content of austenitic stainless steel is between 17%-20%, the Ni content is between 8%-16%, and the C content is generally less than 0.12%. The austenite transformation zone is enlarged mainly by adding Ni elements so that they can be at room temperature. Obtain the austenite structure.

Compared with other stainless steels, austenitic stainless steel has better corrosion resistance, plasticity, toughness, processing and formability, welding performance, and low-temperature performance. Therefore, it is the most widely used in various fields, and its usage accounts for about all stainless steel. About 70% of the amount.

In the field of petroleum and petrochemical, austenitic stainless steel has greater advantages in strong corrosive and low-temperature media, such as internal components with higher corrosion resistance, especially in intergranular corrosion environments, such as heat exchangers/pipes, Low-temperature liquefied natural gas transmission pipelines, urea, sulfur ammonia and other production vessels, flue gas dust removal and desulfurization devices.

Austenitic stainless steel has excellent corrosion resistance and high comprehensive performance. It solves the shortcomings of weak corrosion resistance of ferritic and martensitic stainless steel, and insufficient strength and wears resistance of austenitic stainless steel. In the petroleum and petrochemical field, it is mainly used in seawater corrosion-resistant offshore oil platforms, acidic components and equipment, especially pitting-resistant components.
