ASTM A387 Grade 11 is a chromium-molybdenum alloy steel plate that has principal use in high-temperature conditions. The presence of chromium in the alloy enhances resistance to oxidation, while molybdenum contributes to high-temperature strength and corrosion resistance. Therefore, it is a highly appropriate material for boilers, pressure vessels, and heat exchangers.
