Boiler and heat-resistant steels retain strength and oxidation resistance at elevated temperatures. PacSteelCorp supplies grades to standards such as ASTM A387/A335 (Cr-Mo alloys) and EN 10028-2 for boilers, superheaters, steam pipework and power-plant components. Chromium and molybdenum additions provide creep strength and high-temperature stability. The standards below list representative grades with chemical composition and mechanical properties for high-temperature service.
