What is TP321?

TP321 is austenitic stainless steel, refers to the stainless steel with austenitic organization at room temperature. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but the strength is low, it is not possible to strengthen it through phase transformation, and can only be strengthened through cold working, such as the addition of sulfur, calcium and other elements, it has good machinability. As austenitic stainless steel has a comprehensive and good overall performance, in all walks of life to obtain a wide range of applications. Austenitic stainless steel was introduced in Germany in 1913, has been playing the most important role in stainless steel, its production and use of about 70% of the total production and use of stainless steel. Steel number is also the most, China commonly used austenitic stainless steel grades there are more than 40.
