EN 1.4362, X2CrNiN23-4, UNS S32304 Details

Seamless circular steel tubes for mechanical and general engineering purposes - Technical delivery conditions - Part 2: Stainless steel

The steel supplied most often in the form of bars, plates and pipes is used in the manufacture of tanks for chemical compounds, responsible screws, sleeves, valves, shafts, stirrers, desalination systems, flanges, pumps, pipelines as well as radiators and for the construction of aircraft structures.Duplex 1.4362 / X2CrNiN23-4 has a high resistance to acid environments and stress corrosion. It is a great, much better alternative to austenitic 316L / 1.4404 stainless steel and can also be used interchangeably with 1.4460 / X3CrNiMoN27-5-2. Grades are used in the paper, petrochemical and fuel industries, chemical, shipbuilding, nitrogen, aerospace, construction, heat and power generation and cryogenic industries.
