Description Duplex valves. Corresponding Standards for duplex are:

• EN/DIN 1.4462 X2CrNiMoN22.5.3 • AFNOR Z2CND22.05Az • AISI A182 F51 • UNS ASTM A276 S31803 / S32205 • BRANDS SAF 2205 - SANMAC • URANUS 45N • EN (10283) 1.4470

Duplex stainless steel is among various metals used in corrosion-resistant applications. Duplex's machining rate of travel is similar to that of 316 stainless steel with high-speed steel tooling, and duplex requires fewer machining labor hours than high-nickel alloys. Duplex alloys are in a class with several other materials for various types of corrosion resistance. Some of the corrosive environments listed below depict these differences. There are many more types of corrosive conditions but these are some for which stainless and nickel alloys are suitable.
