High strength steel plates A514 grade E vs A514 grade H

High strength steel plates a514 grade E and High strength steel plates a514 grade H owned high yield strength above 690Mpa and high tensile strength within 760-895Mpa,for steel plate a514 grade e and a514 grade h thickness up to 3/4 inches (20mm),the specification A514/A514M requires Brinell Hardness number 235 to 293.

Steel plate A514GRE have a higher Manganese percentage and no requirement contains for Nickel alloy element.However A514grH have a lower Manganese contains and require 0.3-0.7 % contains for Nickel when offering.Xinsteel offer A514GRE steel plates and A514GRH steel plates from our stock with thickness 6-150mm,width 5 feet to 10 feet,length 20ft to 40ft.
