■ Overview
Low alloy steel plate A572 Grade 50 is the most common steel grade in steel standard A 572/A 572M.Steel plate A572Gr50 owned the minimum yield strength at 345 Mpa and the minimum tensile strength at 450 Mpa.Generally for the thickness equal and belows 40mm of steel plate A572 Grade 50,we suggest rolling under As rolled is ok,for the heavy steel plate above 40mm,normalized heat treatment rolled is better for steel plate A572 Grade 50.Now Xinsteel can roll the maximum thickness of steel plate A572Gr50 reach till 450mm for guarantee the steel property totally according to A572/A572M.
