Ductile Ni Resist Alloys
These Ductile Ni Resist grades are austenitic ductile iron grades that provide good hardness, dampening, and some corrosion resistance. They provide reasonable strength and dimensional stability at higher temperatures.
| Ductile Ni Resist Alloy Properties | |
|---|---|
| Representative Alloys | D-2, D-2B, D-2C, D-2S, D-3, D-3A, D-4, D-5, D-5B, D-5S |
| Applications | Where a combination of toughness, corrosion resistance, and wear/erosion resistance is needed; with certain alloy additions, these alloys also do well in higher temperature applications |
| Limitations | Very difficult to weld |
| Typical Uses | Slurry pumping applications, Cylinder liners, pistons, bearings, glands |
| Machinability | Fair to good |
| Weldability | Very difficult to weld and requires customer consent to weld |
| Corrosion Resistance | Good in mild acids/alkalies, sea water but fair less than stainless steels |
