Super duplex stainless steel S32760 ( F55 ) brief introduction

S32760 ( X2CrNiMoCuWN ) strength and strong resistance to corrosion, mainly used in chemical processing, petrochemical and submarine equipment. It has a strong resistance to chloride compound corrosion resistance, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nitrogen content 's it has high resistance to pitting corrosion, crevice corrosion and general corrosion ability. Application areas: Petroleum and natural gas industries offshore platform equipment, heat exchanger, water equipment, fire fighting equipment chemical processing industry, vessels and piping industry desalination plants, high pressure RO plants and submarine pipeline mechanical components ( high strength, corrosion resistant component.
