A387 Grade 5 Class 2 (A 387 Gr 5 Cl 2) material is a chrome molybdenum alloy steel plate intended specifically for use in weldable carbon steel pressure vessels at elevated temperatures. Added molybdenum gives the material greater temperature tensile strength and the chromium provides improved corrosion resistance.

A387 Grade 5 Class 2 pressure vessel plates are high-performance alloy steel plates that include molybdenum and chromium as the main content. In addition to these are alloyed with other content such as manganese, nickel, and silicon.
The A387 Grade 5 Class 2 plate alloy steel products are finally ready for the delivery hence to maintain the quality of the product during shipping these are appropriately packed with standard packaging material. The products are properly wrapped in waterproof plastic wrappers and then packed in wooden boxes, wooden cases, wooden cartons, and pallets. At last, the products are labeled with suitable product details like size, length, thickness, grade, trademark, length and specifications.
