JIS G 3101 SS400 is one of the most commonly used hot rolled general structural steel.
Ss400is a Japanese brand of ordinary steel products,
JIS G 3101 SS400 steel chemical composition:
| Grade | C max | Si max | M max | P max | S max |
| ss400 | - | - | - | 0.050 | 0.050 |
JIS G 3101 SS400 steel mechanical property:
| Grade | Yield Strength(Mpa) | Tensile Strength(Mpa) | Elongation(%) |
| ss400 | 245 | 400 | 21 |
Ss 400 has no chemical composition assigned the, In addition to iron, the main ingredients are C, Si, Mn, S, P, C, Mn, Si is the mechanical properties of the product element plays the leading role, S, P is harmful to the steel element, the lower the better.
SS400 requires only S, P < 0.050, SS400 tensile strength for 400 - 510 mpa, yield strength of 245 mpa, and SS400 named to the tensile strength.
