Remark :
- Carbon Equivalent (%) = C+Mn/6 + Si/24 + Ni/40 + Cr/5 + Mo/4 + V/14 (JIS Standard)
- Carbon Equivalent (%) = C+Mn/6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15 (AS, ASTM Standard)
- Chemical Composition on sensitivity of welding crack = C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/10 + 5B
- Bend test on material grades SS400, SS490, SS540
- Additionnal chemical composition controls for material under grade A992 are as follows :
Ni (max) = 0.45, Cr (max)= 0.35,Mo (max.) = 0.15 and Mn/S (min.) = 20
* Nitrogen control excluded |
