Steel plate S420M is low alloy steel plate which is mainly used to manufacture the plants of factory,the common constructure and construction machinery and equipment.For S420M structural steel,M is for heat treatment under TMCP.For the thickness equal and belows 16mm,the minimum yield strength of steel plate S420M shall be 420 Mpa,and tensile strength of steel plate S420M shall be within 520-680 Mpa.Now steel can offer the maximum thickness of S420M steel reach till 400mm and with the unit weight about 28 metic tons.
