ASTM A276 316 Introduce
ASTM A276 316 steel is an alloy of iron, chromium and nickel. The alloy is classified as a stainless steel since it contains at least 10.5% chromium. ASTM A276 316 steel has a very high corrosion resistance and also possess good mechanical properties. This makes it an ideal choice for applications requiring extreme toughness and strength. ASTM A276 316 steel can be heat-treated to obtain the desired hardness and strength.
Smelting temperature:1585°C - 1599°C
Application:Stainless steel bars and profiles
