S355ML steel plate meaning and chemical composition

S355ML steel plate is a hot-rolled weldable fine-grained structural steel, belonging to low-alloy high-strength steel plate. For S355ML, S is the meaning of structural steel, 355 indicates that the minimum yield value of the S355ML plate with thickness less than 16mm is 355MPa, and M represents the delivery state, and capital letter L indicates the impact temperature is not less than -50 degrees. S355ML non-alloy structural steel plate executive standard: EN10025-4.

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 is mainly used in the load-bearing parts of low-temperature welded structures such as bridges, sluices, storage tanks, water supply tanks, etc.
