Description

Nitronic® 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a high temperature alloy for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S. The additions of silicon and manganese have given the 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. The 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.
