ASME SA302 Grade C, SA302 Grade C steel, SA302 Grade C steel plate
2013年9月4日 by admin
Adopt standard: ASME SA302
Sell steel grade: SA302 Grade A,SA302 Grade B,SA302 Grade C, SA302 Grade D steel grade
SA302 Grade C steel plates shall be killed and conform to the fine grain size requirement of specification A 20/A 20M.
SA302 Grade C is Mn- Mo-Ni alloy steel grade, the same with SA302 Grade D. SA302 Grade C min yield strength is 345Mpa. When normalized SA302 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.
Gangsteel supplied SA302 Grade C to export many years. We have contacted the technical department of wuyang mill, from ingot or billet steel, to hot rolled process and normalized treatment, each item in manufacture, Gangsteel have the person to tract for our customers in order to in the fastest delivery time.
