YUS 270, Super-austenitic Stainless Steel, for Piping and Tubing Applications

The paper gives the properties of YUS 270, super austenitic stainless steel con- taining 6% Mo, for piping and tubing applications. The steel has excellent corrosion resistance in chloride rich environment such as seawater and HCl and also in sulfu- ric acid environment. The maximum allowable tensile strength values for the steel have been prepared for power boiler use. Therefore, YUS 270 pipes and tubes are promising materials for desalination plants, food processing plants that deal with high salt concentration materials and heat exchangers in coal-fired power plants and incineration plants.
