    Overview of Q235 Steel Plate Specification

    Q235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA.sp.info Q235 Steel Plate Equivalent Steel Standard-ASTM A36A36 steel plate is similar to Q235B steel plate, it is one Q235b equivalent steel standard, another one is SS400. While the difference between A36 and Q235B is as follows:Different Yield Point (A36=250MPa, Q235B=235MPa); Different Tensile Strength (A36=400-550MPa, Q235B=375-500MPa);sp.info 1 2711 steel chemical composition metal properties - Hot The chemical composition of this steel includes C, Si, Ni, Mn, S, P, Cr and Cu (1). This steel is widely applicable.sp.info Q355 Steel Properties, Composition & EquivalentQ355 steel has good mechanical properties, good weldability, hot and cold processing properties and corrosion resistance. Can be used to manufacture ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting transport machinery and other higher load welded structural parts.
