What kind of material is stainless steel 329? ? ?
Stainless steel 329 is an American standard duplex stainless steel material. Corresponding to the new domestic brand: 06Cr26Ni4Mo2, corresponding to the old domestic brand: 0Cr26Ni5Mo2. Japanese standard SUS329J1, American standard UNS S32900.
S32900 (2605) duplex stainless steel is a kind of high hardness and high strength austenitic ferrite duplex stainless steel. It is a super duplex stainless steel with high resistance to localized corrosion and stress corrosion of chloride and can be welded; it has good plasticity and It has toughness, weldability and corrosion resistance, and has good corrosion resistance in oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment linings, transportation pipelines, and nitric acid-resistant equipment parts. It is suitable for acid-resistant equipment. Seawater corrosion equipment, etc.
