Source：Yusheng steel

Manganese-molybdeum-nickel alloy steel plate SA302 Grade C and SA302 Grade D which under steel specification standard ASME SA302 / SA302M,the best similar steel grades A302 Grade C and A302 Grade D under standard ASTM A302 / A302M.Generally the heat treatment for pressure vessel steel plate SA302 Grade C and SA302 Grade D shall be hot rolled,Normalised is ok when the end users required in their purchase orders.As for pressure vessel steel plates, YUSHENG STEEL insist doing Ultrasonic test on each plate for improve the steel properity,the according standard shall be chosed from ASTM A435/A435M,A577/A577M,A588/A588M and European UT standard classes.

Now YUSHENG can roll the maximum thickness for steel plate A302 Grade C and A302 Grade D in 300 millimeters,and also gurantee the steel properity including mechanical properity and chemical composition completely according to the standard A302 / A302M.Now we are the only one supplier can do this gurantee in China.
