ASTM A36 steel plates and A36 equivalent materials steel plate

ASTM A36 steel plates are one of the most popular mild steel plates in the world. As we know, a lot of countries have their own national standards for steel production. So ASTM A36 steel plates will have a lot of equivalent materials, such as A283C, FE360B, E24-2, Chinese material Q235B, Japan material Ss400 and SM400A, European material EN S235JR, Germany material DIN ST37-2, etc. Those equivalent materials have little difference in chemical composition and mechnical properties, below are some of the grades comparison for your reference:
