ASTM A331 Grade E9310 Introduce

ASTM A331 Grade E9310 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:1764°C - 1974°C

Application:Cold rolled alloy steel rod
