X2CRNIMOWN25-7-4 equal material: NAS 75N, 1.4501, S32760, SUS329J2L
X2CRNIMOWN25-7-4 is a kind of high alloying super duplex stainless steel, mainly used in all kinds of strong corrosive environment. Its strength and corrosion resistance is stronger, is mainly used in chemical processing, petrochemical and underwater equipment.It has strong ability to resist chloride compound corrosion, high thermal conductivity and low thermal expansion coefficient. High chromium, molybdenum and nitrogen content in it has the very high corrosion resistance to pitting corrosion, crevice corrosion and general ability.
