Comparasion with SA302GrC steel plate and SA302GrD steel plate

SA302GrC steel plate and SA302GrD steel plate are both from U.S.specification ASME SA302/SA302M,SA302GrC steel plate has the same yield strength and tensile strength as SA302GrD steel plate.Comparasion with SA302GrC steel plate and SA302GrD steel plate,the main different is Ni% contain,SA302GrC steel plate contains 0.4-0.7% Ni,however SA302GrD contains a higher Ni with 0.7-1.0%.

Xinsteel stock hundreds tons Mo-Ni alloy steel materials as SA302GrA steel plate,SA302GrB steel plate,SA302GrC steel plate and SA302GrD steel plate with heavy thickness.Ultrasonic examination with ASME standard done for these alloy steel plates stock also.
