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.
|ILLIUM® P, ILLIUM® PD, CD4MCu, CD3MN (2205)
|Where higher strength is advantageous; resisting erosion and corrosion
|Some grades difficult to produce in heavy sections
|Pump parts, mixers
|Good to fair. Post-weld heat treatment required
|Subject to stress corrosion cracking in some media
