ASTM A131/A131M A131 Grade EH36 Introduce
ASTM A131/A131M A131 Grade EH36 is formulated using a combination of various steel alloys, such as aluminum, chromium, molybdenum, nickel, and vanadium. The alloying elements impart improved strength, especially in the areas of toughness, fabricability, and weldability. The addition of chromium and molybdenum produces a strongly resistant corrosion product, which helps to increase the life of the final product.
Smelting temperature:1982°C - 1986°C
Application:Structural steel for seagoing
ASTM A131/A131M A131 Grade EH36 Material Mechanical Properties
ASTM A131/A131M A131 Grade EH36 steel has a high tensile strength rating. This type of steel can be bent, twisted, and stretched without losing its strength.
