Alloy 321 is a titanium austenitic SS having high corrosion resistance, great pitting resistance and excellent strength at high temperature and strength. The grade has phenomenal resistance to intergranular corrosion in the chromium carbide precipitation environment. The grade maintains low temperature toughness and thus can be widely used in the high temperature environment. The Stainless Steel 321/321H Flanges exhibit great creep resistance property and cannot be hardened by any heat treatment since it can be done only by cold working.
Some of the other general characteristics found in the grade are high oxidation resistance at high temperature, stabilization in welded temperature and can resists the stress corrosion cracking environment.
Champ Steels provides relevant documents that help the buyers to counterpart the product with the offered documents. Testaments such as welding procedure specification, fumigation certification, QAP, heat treatment chart, lab reports and certificate of origin are some of the documents.
Besides, the industry offers tests certifications such as self-inspection certificate, radiography tests reports, raw material reports and third party inspection certificates are some of the certifications offered along with the Stainless Steel 321/321H Flanges.
