PRODUCT DETAILS
ASME SA387 GR.22 CL2 Pressure Vessel Steel plate Descriptions:
SA 387 GR.22 CL.2 PLATE is having chromium of 2.25% and molybdenum of 1% and ability to work in 600 Deg C temperatures surrounding effectively. The molybdenum and chromium steel plates are working effectively at different temperature continually offering best performance. The addition of molybdenum in SA 387 alloy is increasing the tensile strength of the plates at greater temperature. Also, it is providing excellent corrosion resistance ability and oxidation as well by increasing the lattice strain. This is effectively stopping the corrosive agent from iron dissolving and gives good heat resistance ability and becomes a good choice for gas surrounding. Also, it has good weldability. Thus, this plate is highly demanded globally.
