ASTM A202 Grade A is a medium‑strength, chromium‑molybdenum alloy steel plate designed for welded pressure vessels operating at intermediate temperatures. With good creep resistance and stable mechanical properties, A202 Grade A is widely used in petrochemical, power generation, and industrial boiler applications. It offers reliable performance in environments requiring moderate heat resistance and structural integrity.
