stainless steel 321 It is used in outdoor machinery in the fields of chemical, coal and petroleum mines, where there is a high demand for intergranular corrosion, and heat-resistant building materials and parts with heat treatment problems.

efficiency

Ti is a stable component in 321 stainless steel plate. It is also a kind of thermal heating steel, which is more than 316L stainless steel plate in such aspects as high temperature. 321 stainless steel plate has good corrosion resistance in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing agents. It is used for the production of lining and conveying of wear-resistant container pipes and wear-resistant equipment.

321 stainless steel plate is a kind of Ni-Cr-Mo stainless steel plate, which has similar properties to 304 stainless steel plate, but due to the addition of titanium, it has a higher resistance to grain corrosion and higher temperature strength Due to the addition of titanium, chromium carbide formation can be effectively controlled.

321 stainless steel plate has excellent high temperature stress resistance properties and high temperature creep resistance performance and stress mechanical properties are superior to that of 304 stainless steel plate.

The difference between 321 stainless steel plates

and other stainless steel plates

321 contains titanium.

316 contains molybdenum.

304 does not contain titanium and molybdenum.

Mo2Ti is available in both molybdenum and titanium. The properties of 316L are the best and the properties of 321/304 are common.
