ASME SA 387 Grade 91 Class 1/2 is a chromium-molybdenum alloy steel plate crafted for high-temperature service. It features around 9% chromium and 1% molybdenum, along with vanadium (0.18–0.25%), niobium, nitrogen, and controlled carbon (0.08–0.12%). These components boost its creep resistance, oxidation resistance, and mechanical stability at elevated temperatures. The material boasts a minimum tensile strength of 585 MPa and a yield strength of 415 MPa, along with impressive creep-rupture strength. With good weldability and resistance to thermal fatigue, this grade is perfect for boilers, pressure vessels, and heat exchangers.
