What is the chemical composition of A302GrA steel

　　A302GrA steel is manganese-molybdenum alloy steel for pressure vessels and welded boilers. ASTM A302 steel grades have different tensile strength levels. For example, A302GrA steel plate have 75-95 ksi[515-655 MPa] tensile strength. Below is the chemical analysis of A302 Gr.A steel.

　　Chemical composition(%) of A302GrA steel:

　　The carbon content has different requirements under different thickness as follows: Carbon: 0.20 max. In thickness up to 1inch[25mm]; Carbon: 0.23max. In thickness over 1 to 2inch[50mm]; Carbon: 0.25max. In thickness over 2inch[50mm].

　　Manganese: 0.95-1.30, Phosphorus: 0.025max., Sulfur: 0.025max., Silicon: 0.15-0.40 max., Molybdenum: 0.45-0.60 max.

　　As a leading supplier of A302GrA pressure vessel plates, we can supply A302GrA plates up to thickness 150mm.

　　A302GrA steel is widely used in petroleum, chemical, power station, boiler and other industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders Equipment and components such as high-pressure water pipes and water turbine volute of hydropower stations.
