EN10025-4 S275M weldable fine grain structural steels

S275M steel is a kind of TMCP( Thermo Mechanical Control Process) rolled weldable fine grain structural steels.So, it can be used into the steel structural or welded vessel or pressure vessels. At the same time, S275M also can be used in the offshore or any other applications which request the high tensile strength.

Mechnical property for S275M Structural steel:
Thickness (mm)
S275M ≤ 16 > 16 ≤ 40 > 40 ≤ 63 > 63 ≤ 80 > 80 ≤ 100 > 100
Yield strength (≥Mpa) 275 265 255 245 245 240
≤ 40 > 40 ≤ 63 > 63 ≤ 80 > 80 ≤ 100 > 100
Tensile strength (Mpa) 370-530 360-520 350-510 350-510 350-510
