BS700MCK2 steel Chemical Composition :
| Grade | C | Si | Mn | P | S | Alt | B |
| BS700MCK2 | ≤0.12 | ≤0.60 | ≤2.10 | ≤0.025 | ≤0.010 | ≥0.015 | ≤0.005 |
BS700MCK2 steel Mechanical Properties :
| Grade | Thickness (mm) | Yield Strength Re(MPa) | tensile strength Rm(MPa) | Elongation A5(%) | Shock Value IE (J) |
| BS700MCK2 | 3-8 | 700-860 | 780-920 | 15-21 | 40-100 |
| (8)-12 | 685-820 | 790-900 | 15-21 | 60-150 |
BS700MCK2 Delivery status: BS series adopt high-strength steel-rolled (TMCP) delivery.
Good Weldability --- carbon equivalent(Ceq) and weld crack sensitivity index(Pcm)
| Grade | Performance carbon content C(%) | Performance carbon content Ceq | Welding sensitivity index performance Pcm |
| BS700MCK2 | ≤0.08 | ≤0.47 | ≤0.21 |
Ceq = C + Mn/6 (Cu + Ni)/15 + (Cr + Mo + V)/5
Pcm =C + Si/30 + (Mn + Cu + Cr)/20 + Ni/60 + Mo/15 + V/10 + 5B
