S355ML steel is a kind of TMCP( Thermo Mechanical Control Process) rolled weldable fine grain structural steels. The delivery condition for S355ML must be TMCP rolled way with Low temperature impact test. M means -20 min degree impact test. ML means -50 min degree impact test.
EN 10025 S355ML steel have the good weldable and fine grain structural property. So, it can be used into the steel structural or welded vessel or pressure vessels. At the same time, S355ML also can be used in the offshore or any other applications which request the high tensile strength.
Standard : EN 10025-4
Dimension range : 2-150mm * 1000-3800mm * 3000-18000mm
