WCD4™ is a specially processed duplex stainless steel that is chemically similar to ASTM A890 (cast material) or UNS S32550 (wrought material) but with significantly improved mechanical properties and corrosion resistance.

WCD4™ is ideal for erosion-corrosion applications in extremely corrosive environments. Pump wear parts made from WCD4™ are expected to have exceptional wear life due to its increased hardness and improved corrosion resistance.
