Carbon structural and high strength low alloy steel

Common carbon structural steel also be called Mild steel. This kind of steel has very wide use. Because of the low Carbon content and without alloy element, carbon structural steel has the proper tensile strength, good toughness, plasticity,processing property. Carbon structural steel usually be rolled into steel plates, shaped steel and profile steel, which usually used to build workshop,bridge,vessels and so on .The delivery station usually are hot rolled,control rolled, or Normalized.

Carbon structural and high strength low alloy steel

The main grade of common carbon structural steel are :
EN10025(93):S185,S235JR,S235J0,S235J2,S235J2G3,S235J2G4,
EN10025(90): Fe310-0,Fe E360B,Fe E360C,Fe E360D1,Fe E360D2,
DIN17100: St33,ST37-2,ST37-3U,St37-3N
ASTM:A283GrA/B/C/D,A284GrC/D,A36,
JIS3101:SS330,SS400,SS490
JIS3106:SM400A/B/C

Low alloy high strength steel also can be called common low alloy steel,low alloy structural steel. Low alloy structural steel's total alloy content usually is not more then 3% .Except for Si and Mn, there is V,Ti,Nb,Al,Cr,Ni,Re,N and so on.

The main steel grades in Carbon and low alloy steel are like:
EN10025(93):S355JR,S355J0,S355J2,S355J2G3,S355J2G4,S355K2G3,S355K2G4,S275JR,S275J0,S275J2,S275J2G3,S275J2G4.
