ASTM A204 Grade B is a chromium-molybdenum steel alloy that mainly consists of carbon (0.05–0.15%), chromium (0.9–1.2%), molybdenum (0.45–0.60%), along with trace amounts of manganese, silicon, and nickel. This unique composition provides excellent high-temperature strength, toughness, and resistance to oxidation and creep. The alloy showcases impressive mechanical properties, including high tensile and yield strength, impact resistance, and durability under thermal stress. Smith Fittings offers ASTM A204 Grade B Sheets and Plates with precise thickness and consistent quality, making them perfect for fabricating boilers, pressure vessels, and other high-performance engineering applications.
