SA302GrB steel plate is one kind Molybdenum alloy steels in ASME SA302/SA302M,SA302 Grade B is totally equal to A302 Grade B in ASTM A302/A302 steel specification.
Products Description
A302 Grade B is a manganese-molybdenum alloy steel plate specifically designed for welded boilers and other pressure vessels. It is used in industries like petroleum, chemical, and power generation to manufacture equipment such as reactors, heat exchangers, and storage tanks. The material has a minimum yield strength of 345 MPa and a tensile strength of 550-690 MPa.
SA302 Grade B is a manganese-molybdenum alloy steel plate used for welded boilers and other pressure vessels. It has a minimum yield strength of 345 MPa (50 ksi) and a tensile strength of 550-690 MPa (80−100 ksi). The steel is typically supplied in an as-rolled condition, though it can be normalized or stress relieved if specified.
