304 Hot Rolled Stainless Steel Sheet Plate Thickness 3mm - 50mm


300 Series stainless steels are classified as austenitic, and are hardenable only by cold working methods. These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying additions. Type 304 is the most widely used alloy of all stainless steels. 300 Series Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain.

Stainless steel Bright and annealing (BA)

And the copper alloy is easily oxidized during the heat treatment. In order to prevent oxidation and improve the surface quality of the workpiece, it must be annealed in a protective atmosphere or vacuum, so-called bright annealing. The protective atmospheres commonly used in the heat treatment of copper and copper alloys are water vapor, ammonia decomposition, incomplete combustion and dehydration of ammonia, nitrogen, dry hydrogen and partially combusted gas (or other combustible gases). Can be selected according to the type,composition and requirements of the alloy.
