Duplex stainless steel W-NR.1.4410

Equal material:2507 duplex stainless steel,UR 47N+, S32750, W-NR.1.4410, X2CrNiMoN25-7-4

SAF2507 duplex stainless steel molybdenum chromium alloy by 25%, 25% and 7% of nickel. Its strength and corrosion resistance is stronger, SAF2507 duplex stainless steel is mainly used in chemical processing,petrochemical and underwater equipment. It has stronger ability to resist chloride corrosion, high thermal conductivity and low thermal expansion coefficient. High chromium, molybdenum and nitrogen content in it have a high resistance to corrosion pitting corrosion, gap and the ability to uniform corrosion.
