We can provide our clients with competitive price and best services. We also focus on the after-sale service of our customers, we hope offer a best experience for our clients.
321 stainless steel strip is a Ni-Cr-Mo austenitic stainless steel material with properties very similar to: 304 stainless steel strip. However, due to the addition of titanium content in the alloy, it has excellent resistance to intergranular corrosion and high temperature strength, which effectively controls the formation of chromium carbide. 321 austenitic stainless steel strip has good corrosion resistance in air. However, the "stainless steel" of 321 stainless steel is not absolute. Due to the special use environment, 321 stainless steel will also corrode. Factors such as medium concentration, PH value, and temperature have a great influence on corrosion resistance.
