Introduction
Specification

Product description

Type 321 Stainless Steel is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. This titanium addition reduces or prevents carbide precipitation during welding and in 800 - 1500°F service. It also improves the elevated temperature properties of the alloy. Type 321 provides excellent resistance to oxidation and corrosion and possesses good creep strength. It is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 800 - 1500°F.

Applications

Typical applications of 321 stainless steel include:Aircraft exhaust manifolds;Expansion joints;Bellows;Furnace parts;Heating element tubing;Heat Exchangers;Woven or welded screens for high temperature mineral processing;Spiral Welded tube for burner pipes and flues
