Stainless Steel Sheet/Plate 304 Annealed is normally used for aerospace, food and beverage, machinery, architectural, chemical, and cryogenic applications. 304 steel has a Rockwell B hardness of 70; for reference, the Rockwell B hardness of copper, a soft metal, is 51. 2. 304, the most popular stainless alloy in the world, maintains its properties in high temperature situations. BROWSE CATALOG. Type 304 stainless steel annealing temperature range is 1010-1065 C (1850-1950 F),1040 C (1900 F) is recommended and then rapidly cooled. One notable difference between 304 and 316 stainless steel is their levels of nickel and chromium. The former grade usually has a higher chromium content while the latter generally contains more nickel. About 316 Stainless Steel 8.00-10.50. 18.00-20.00. Initially the cold worked state is discussed, with special emphasis on the formation of deformation Applicable specifications require the following properties of sheets in the annealed condition: 302 Tensile Strength - 75.000/110.00 psi Elongation in 2"( 0.15" Thick and Under) - 40% Min. -. The Alloy 304L is most well-liked for use in such media within the welded condition because the low carbon level enhances resistance to intergranular corrosion. As famous in 304 stainless-steel, the alloy reaches its melting level at the 2,550 F 2,650 F (1399 C 1454 C) vary. In stock and ready to ship.
