Structural Steel can be provided as the following types :
1. Common carbon structural steel, also be called as Mild steel. Common carbon structural steel means the material whose yield strength is less than 295MPa with ordinary application like structural parts in building, bridge, ship , automobile and so on.
The popular material of Common carbon structural steel are : ASTM A36, ASME SA36, ASTM A283, ASME SA283, ASTM A570, ASTM A573, BS EN10025-2 S235JR/J0/J2/JR,S275JR/J0/J2, DIN17100 Ust37-2, ST37-2, ST37-3, ST44-2, ST44-3, JIS G4051-1, JISG3101 SS400, SS490, SS540, JIS G3136, JISG3106 SM400A/B/C, SM490A/B/C
2.High strength and low alloy structural steel, mainly material are: ASTM A572, ASME SA572, ASTM 1011, BS EN10025-2 S355JR/J0/J2/K2 S450J0, DIN 17100 ST52-3, ST50-2, ST60-2, ST70-2, JIS G3101 SS540, JIS G3106 SM520B/C, SM570, ASTM A709
5.Alloy structural steel : BS EN10083, DIN EN10028-2, JIS G4053
7. Low carbon Mild structural steel for drawing : BS EN1011, DD11/12/13/14, ASTM A1008, ASTM A1006, DIN EN10130 DC01/02/03/04/05/06, JIS G3141, JIS G3131
