300 Series Stainless Steel

301 Stainless Steel
Type 301 Stainless Steel is an austenitic chromium-nickel stainless steel that provides high strength and good ductility when cold worked. The chromium and nickel contents are lowered to increase the cold work-hardening rate. This generates higher tensile strengths when cold rolled with a lower loss of ductility than with Types 302 and 304. The grade is essentially non-magnetic when annealed. When cold worked, it becomes slightly more magnetic than other standard austenitic stainless steels. Cleveland Metal is your source for 301 stainless steel.

304 and 304L Stainless Steel
Type 304 Stainless Steel is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

316 and 316L Stainless Steel
Type 316 Stainless Steel is an austenitic chromium nickel stainless steel containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Properties are similar to those of Type 304 except that this alloy is somewhat stronger at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids; acid sulfates and alkaline chlorides. Type 316L Stainless Steel is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation in the heat affected zone during welding.

321 Stainless Steel
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 – 1500F 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 – 1500F.
