ASME SA 387 Grade 12 Class 1/2 is a chromium-molybdenum alloy steel that contains about 1% chromium and 0.5% molybdenum. It also includes elements like carbon (maximum 0.15%), manganese, silicon, phosphorus (maximum 0.035%), and sulfur (maximum 0.035%). This blend gives the steel good corrosion resistance and moderate strength at high temperatures. It boasts a tensile strength ranging from 415 to 585 MPa and a yield strength of about 220 MPa. Known for its excellent weldability, creep resistance, and thermal stability, SA 387 Gr. 12 Cl. 1/2 is well-suited for long-term use in moderately high-temperature settings.
