■ Overview
A302 Grade C,A302GrC steel plate,A302GrC steel sheet stock is Manganese-molybdenum-nickel alloy boiler steel plate.The steel of A302 Grade C shall be killed and shall conform to fine grain size requirements. The boiler steel plate A203 Grade C shall be subjected to tension test to determine the tensile strength, yield strength, and elongation.When rolling A302 Grade C steel plate under steel guide NACE MR0175,HIC test,SCC,SSC test shall be done in our mill lab for gurantee SA302 Grade C steel property.Other additional techincal test,such as PWHT,DWTT,High temperature tension test shall be chosed by the end users if they demand.
