UNS S32707 is a hyper-duplex stainless steel, a high-alloy duplex steel with a PRE value of min. 48*. The grade is characterized by excellent chloride corrosion resistance, combined with very high mechanical strength.
S32707 is particularly suited for use in aggressive environments such as hot chlorinated seawater and for highly acidic, chloride containing media. S32707 has better resistance to pitting and crevice corrosion and higher mechanical strength than all super-duplex stainless steel grades available on the market.
