Scope of Application
The molybdenum composition in ASTM A387 boiler vessel plate can improve its tensile strength at high temperature, and make it have higher oxidation and corrosion resistance by increasing the lattice strain. ASTM A387 Boiler Container Plates are ideal for use in heat-resistant pressure vessels and sour gas environments.
