ASTM B435 UNS N06230 (Haynes 230) – Nickel-Chromium-Tungsten-Molybdenum Alloy for High-Temperature Service
UNS N06230 (Haynes 230) is a nickel-chromium-tungsten-molybdenum alloy specifically engineered for exceptional high-temperature strength, outstanding oxidation resistance, and excellent long-term thermal stability. It combines solid-solution strengthening with a unique lanthanum addition that enhances oxide scale adhesion. This alloy is widely used in gas turbine combustion hardware, transition ducts, and thermocouple sheaths where reliability at temperatures up to 1093°C (2000°F) is critical. 1. Product Specifications & Physical Data ASTM B435 covers UNS N06230 in the form of rolled plate, sheet, and strip for heat-resisting and general corrosive service. The alloy is also available in billet, bar, wire, forging stock, pipe, and tubing, typically supplied in the solution-annealed condition. Available Forms: Plate, sheet, strip, foil, billet, bar, wire, forging stock, welding products, pipe, and tubing . Specifications: ASTM B435 (plate/sheet/strip), AMS 5878 (sheet/strip), AMS...
