ASTM A568/A568M 1008 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 1008 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.
