Duplex Stainless Steel Castings

These grades offer a combination of higher strengths and good corrosion resistance, especially in sea water applications. These alloys also offer good toughness at lower temperatures and the higher strengths provide erosion resistance.

Alloy Properties
Representative Alloys ILLIUM® P, ILLIUM® PD, CD4MCu, CD3MN (2205)
Applications Where higher strength is advantageous; resisting erosion and corrosion
Limitations Some grades difficult to produce in heavy sections
Typical Uses Pump parts, mixers
Machinability Good
Weldability Good to fair. Post-weld heat treatment required
Corrosion Resistance Subject to stress corrosion cracking in some media
