Nitronic 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S. This grade is best known for its wear and galling resistance.

The additions of Silicon and Manganese have given this alloy a matrix to inhibit wear, galling, and fretting even in the annealed condition. Higher strengths are attainable through cold working the material and is still fully austenitic after severe cold-working. This working does not enhance the anti-galling properties as is normal for carbon steels and some stainless steels. The benefit to the cold or hot work put into the material is added strength and hardness, and the wear resistance does not decrease noticeably. Chromium and Nickel additions give it comparable corrosion to 304 and 316 stainless steels, while having approximately twice the yield strength. The high mechanical strength in annealed parts permits use of reduced cross sections for weight, and cost reductions through the use of thinner stock.

Several data sheets are available on the wear compatibility of this alloy with dissimilar couples, as well as self-mated coupled results.

If your galling problem occurs at less than 1500ºF, then you should think about switching to this alloy. Nitronic 60 has a better cost advantage than any other alloy available. Other materials require an additional amount of heat treating to raise their hardness, where NITRONIC 60 is excellent in the annealed condition.
