Huzhou Nickel Alloy Special Materials Co., Ltd.
Super Duplex 2507 is designed for demanding applications which require exceptional strength and corrosion resistance, which are found in chemical process, petrochemical, and seawater equipment. The alloy is used in salt evaporation processes, heat exchangers, and hydrochloric acid environments.
2507 Super Duplex is a high alloy duplex stainless steel with a PRE (pitting resistance equivalent) value of 42.5 minimum. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength.
It is widely used in offshore oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing. The grade is also suitable for hydraulic and instrumentation applications in tropical marine environments.
