ASTM A331 Grade E52100 Introduce
ASTM A331 Grade E52100 is a cold-drawn, low-alloy steel that has a higher yield strength than some other types of steel. The material is also heat-treatable and has excellent weldability, making it suitable for a variety of industrial applications. The steel has a low carbon content range of 0.25-0.30%, making it relatively soft and easy to work with.
Smelting temperature:1688°C - 1278°C
Application:Cold rolled alloy steel rod
