产品描述
INCOLOY alloy 25-6HN is a super-austenitic stainless steel containing 6% molybdenum with properties enhanced by its content of nitrogen. Its high content of nickel results in thermal stability and resistance to stress corrosion cracking. Designated as UNS N08367, alloy 25-6HN directly competes with alloy AL6XN®1. The same ASTM, ASME and NACE specifications cover the alloys. Alloy 25-6HN offers significantly improved strength and corrosion resistance in most environments over conventional austenitic stainless steels such as AISI 304 or 316L. Typical applications include welded tubes for heat exchangers for both chemical processing and marine applications and for desalination systems, flue gas desulfurization equipment for coal-fired power plants and reaction vessels for pharmaceutical production. 1“AL6XN” is a registered trademark of Allegheny Ludlum Corporation.
