Pressure vessel steel plate SA302 Grade A and SA302 Grade B under steel standard ASME SA302/SA302M which is manganese-molybdenum alloy steel plates intended particularly for welded boilers and other pressure vessels.According to their strength levels,there are different grades A302 Grade A,A302 Grade B,A302 Grade C and A302 Grade D.Pressure vessel steel plate A302 Grade A owned tensile strength within 515-655 Mpa,minimum yield strength is 310 Mpa,and pressure vessel steel plate A302 Grade B owned tensile strength at 550-690 Mpa.

For these pressure vessel steel plates, Ultrasonic test have to be done after rolling and the test values and result shall be indicated in our mill certificates.Our mill would issue the original MTC (Mill test certificate) under format EN 10204 3.1 if without the third party inspection. When our end customers ask for doing the third party inspections,we would like to try our best to assistance the third party agents to finish the goods inspection,and finally owned their stamped and endorsed on our original MTCs.
