Duplex stainless steel SAF2507

Duplex stainless steel SAF2507

 Equal material:2507 duplex stainless steel,UR 47N+, W-Nr.1.4410, S32750, 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.
