Leading the World in Stainless Steel Coil Fabrication Excellence
Type 321 is a titanium-stabilized chromium-nickel austenitic stainless steel offering corrosion resistance comparable to 304/304L. This remarkable grade is ideal for applications in the 800-1500˚F temperature range. By incorporating titanium, it is stabilized against chromium carbide precipitation, forming titanium carbides. Type 321 stands out with superior intergranular corrosion resistance, exceptional oxidation resistance up to 1500˚F, and enhanced creep and stress rupture properties compared to 304/304L. It also maintains strength at low temperatures and remains non-magnetic when annealed.
At Daxun Stainless Steel, we ensure full traceability of each stainless steel coil via our advanced ERP system, meticulously documenting type, specification, and origin. We are staunch advocates for industry-wide anti-counterfeiting measures. Our commitment to high precision and quality processing and customization has set the industry benchmark.
