S420ML steel is a kind of TMCP( Thermo Mechanical Control Process) rolled weldable fine grain structural steels. The delivery condition for S420ML must be TMCP rolled way with Low temperature impact test. M means -20 min degree impact test. ML means -50 min degree impact test.
S420ML structural carbon steel cutting plate have the good weldable and fine grain structural property,so S420ML structural steel cutting plate can be used into the steel structural or welded vessel or pressure vessels. And S420ML carbon steel cutting sheet 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
