ASTM A568/A568M 1055 Introduce
ASTM A568/A568M is an American material standard for steel that covers both hot-rolled and cold-rolled carbon steel sheets and strips. It was first issued in 1994 and revised in 2020. ASTM A568/A568M 1055 is used for steel products such as coils, sheets, bars, strips, plates, and structural shapes such as angles, channels and rounds. This material is regarded as high-quality and is specified for a wide variety of purposes.
Smelting temperature:1579°C - 1485°C
Application:Hot rolled and cold rolled high strength low alloy carbon steel sheet
ASTM A568/A568M 1055 Material Mechanical Properties
ASTM A568/A568M is the American Society for Testing and Materials (ASTM) International standard which specifies the requirements for carbon steel, high-strength low-alloy (HSLA) steel for use in structural applications. It covers various grades of HSLA and other steels such as carbon steel, cold-rolled steel and hot-rolled steel.
