When you’re tackling high-temperature environments that demand both strength and corrosion resistance, UNS N06230 alloy steel plate, also known as Haynes 230, is a top contender. Supplied by Gangsteel, a leading stainless steel supplier in China, this nickel-chromium-tungsten alloy is renowned for its exceptional UNS N06230 high-temperature strength and oxidation resistance up to 1150°C (2102°F).
Gangsteel offers UNS N06230 plate, sheet, bar, and custom components, meeting ASTM B435 and ASME SB-435 standards.
Gangsteel page covers the UNS N06230 chemical composition, mechanical properties, equivalent materials, specifications, applications, and competitive UNS N06230 price per kg. Explore our nickel alloy steel grades for related alloys like UNS N06625, UNS N07718, and UNS N06002.
UNS N06230(Haynes 230) is a nickel-chromium-tungsten alloy with approximately 57% nickel, 22% chromium, and 14% tungsten, designed for outstanding high-temperature strength, oxidation resistance, and creep resistance. Its unique composition, including low carbon and additions of molybdenum and cobalt, makes UNS N06230 material ideal for gas turbine components, furnace retorts, and aerospace applications. Compared to UNS N06625, UNS N06230 offers superior creep resistance at extreme temperatures, making it a preferred choice for prolonged high-heat exposure.
Gangsteel’s UNS N06230 alloy steel plate is engineered for demanding high-temperature applications, providing a robust alternative to nickel alloy steel grades like UNS N06002 or UNS N07263.
