Description

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of alloy 2507 super duplex tubing in China. With abundant experience, we warmly welcome you to wholesale customized alloy 2507 super duplex tubing from our factory. For price consultation, contact us.

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 particularly suited for use in aggressive environments such as warm chlorinated seawater and acidic chloride-containing media. 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.
