KSGeneral Structural Steel
2 sizes| KS | JIS | DIN | ANSI/ASTM | Category | Note |
|---|---|---|---|---|---|
| SS400 | SS400 | S235JR | A36 | Structural Steel | Most General Structural Steel |
| SS490 | SS490 | S355JR | A572 Gr.50 | Structural Steel | High Strength Structural Steel |
Key Features
- SS400 is a shared KS/JIS designation for 400 MPa tensile strength; the world's most widely used structural steel
- Equivalent to DIN S235JR (formerly St37) and ANSI A36; interchangeable across standards in most applications
- Good weldability, easy plating/painting, and low cost; the standard base material for general machinery and structures
Key Applications
Machine frames, brackets, plates, bolt/nut material, architectural steel structures
