A302 grade C,A302GrC,A302 Gr C,A302Gr.C Steel Plate
 
Unitedsteel Mill produce super thickness and high quality A302 Grade A steel plates standard specification for pressure vessel plates in alloy steel, manganese molybdenum and manganese-molybdenum-nickel.
 
A302 Grade C steel plates shall be killed and conform to the fine grain size requirement of specification A 20/A 20M.

A302 Grade C is Mn- Mo-Ni alloy steel grade, the same with A302 Grade D. A302 Grade C min yield strength is 345Mpa. When normalized A302 Grade C in thickness 100mm or over in thickness, the cooling rate maybe accelerated by air blasting or liquid quenching to obtain mechanical properties comparable to those developed by normalizing plates in the lesser thickness.
