S355ML steel plate grade analysis

Posted:2021-08-10 17:27:25

S355ML steel plate is a hot-rolled weldable fine-grained structural steel, belonging to the series of low-alloy high-strength steel plates, flat rolled products with a thickness of no more than 120mm and long products with a thickness of ≤150mm. Among them, S is the meaning of structural steel, 355 indicates that the small yield value of the relevant thickness less than 16mm is 355MPa, and M represents delivery status, that is, the meaning of hot rolling. The rule is when the temperature is not less than -50 degrees, the impact is indicated by a capital letter L. S355 is non-alloy structural steel.

Chemical composition of S355ML steel plate:
C≤0.14, Si≤0.5, Mn≤1.6, P≤0.025, S≤0.020, Nb≤0.05, V≤0.1, Al≤0.02, Ti≤0.05, Cr≤0.3, Ni≤0.5, Mo≤0.1, Cu≤ 0.55, N≤0.015

S355ML steel plate executive standard: EN10025-4. S355ML steel plate is delivered in hot rolling state.
