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
