ASTM A331 Grade 5015 Introduce
ASTM A331 steel is a cold-drawn, low-alloy steel that has a higher yield strength than some other types of steel. This grade of steel has a higher tensile strength and yield strength than many other carbon steel alloys, and it is also highly resistant to fatigue and fracture. The material is also heat-treatable and has excellent weldability, making it suitable for a variety of industrial applications.
Smelting temperature:1343°C - 1779°C
Application:Cold rolled alloy steel rod
