Structural steel S355JR, S355J0, S355J2G, S355J2G4 are low-alloy high-strength structural steels that comply with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength of 300-400MPa. S355J2G3 steel is roughly equivalent to GB Q345D. S355J2G3 means that the delivery state is normalized, and the impact energy at -20°C is 27J. G3 and G4 mean the deoxidation method.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ~ 0.75, Mn: 0.20 ~ 0.50, P: 0.07 ~ 0.15, S≤0.03, Cu: 0.25 ~ 0.55 , Cr: 0.30 ~ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet A573 grade 70 carbon steel plate is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The A573 grade 70 carbon steel plate, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
