SS400 material is a structural hot rolled steel in the form of plates, sheets and strips for general structural usage. SS400 material is defined in JIS G3101 standard.
SS400 material Chemical Composition (max %):
| Grade | Chemical Composition, % by weight | ||||
| C. max | Si. max | Manganese | P. max | S. max | |
| SS400 | - | - | - | 0.050 | 0.050 |
SS400 material Mechanical Properties:
| Grade | Yield Strength min. (Mpa) | Tensile Strength MPa |
Elongation min.% | Impact Resistance min.[J] | |||
| Thickness ＜16 mm | Thickness ≥16mm | Thickness ＜5mm | Thickness 5-16mm | Thickness ≥16mm | |||
