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.
|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|
|Weldability||Good to fair. Post-weld heat treatment required|
|Corrosion Resistance||Subject to stress corrosion cracking in some media|
