Product Overview
Haynes-282 Nickel-Based Superalloy Sheet is a premium solution engineered for extreme thermal and mechanical demands in mission-critical industrial applications. As one of the most advanced nickel-based superalloys, Haynes-282 delivers exceptional creep resistance, thermal stability, and oxidation resistance up to 980°C (1800°F), outperforming legacy alloys like Inconel 718 and Waspaloy. This sheet conforms rigorously to ASTM B752 for nickel-chromium-molybdenum-tungsten alloy plate, sheet, and strip — ensuring dimensional accuracy, metallurgical consistency, and traceable quality control. It is also certified under ASME Code Case 2892, enabling its use in ASME Section I and III nuclear and high-pressure boiler components where regulatory compliance is non-negotiable. Designed for precision custom fabrication, this material supports complex forming, welding (GTAW/PAW), and machining — making it ideal for OEMs and Tier-1 suppliers in aerospace, power generation, and petrochemical sectors seeking reliable high-temperature alloys.
