P460QL2 Pressure Vessel And Boiler Steel Plate
P460QL2 boiler plate is a low alloy steel with a minimum yield strength typically between 690-760 MPa, a high tensile strength of 920-1050 MPa and an elongation of 11-16%. Composed primarily of elements such as chromium, molybdenum and nickel, as well as small amounts of vanadium and copper, P460QL2 vessel plate has a high strength-to-weight ratio and good weldability.
