1.4501 X2CrNiMoCuWN25-7-4 Austenitic-ferritic Stainless Steel
Introduce
The 1.4501 is an austenitic-ferritic, high-alloy, low-carbon chromium nickel molybdenum tungsten (super duplex) steel that is resistant to chloride-containing media and can be used in areas where traditional duplex steels are no longer adequate. Due to higher contents of chromium and molybdenum in combination with tungsten, the PREN-values of the material are from 40 to> 46 J with good impact values and wear resistance properties at -40 ° C. The steel 1.4501 – ASTM A182 F55 – Superduplex: UNS S32760 is resistant to seawater, has a high resistance to surface, as well as hole and crevice corrosion and is suitable to use in sulfuric acid.
