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.
Nitronic 60 Alloy Stainless Steel Applications
Due to the material's good corrosion and wear resistance and its excellent high temperature oxidation resistance, Nitronic 60 is used in a wide range of applications including military aircraft, deep-space exploration, bridge building and various medical applications. See below for a few specific examples:
- Surgical Scissors
- Cartilage Cutters
- Wear Pins
- Pin and hanger expansion joints for bridges
- Marine shafts
- Valve trim
- Threaded assemblies
Corrosion Properties
The corrosion resistance of Armco NITRONIC 60 Stainless Steel falls between that of types 304 and 316. However, experience shows that in a wear system, a galling or siezure failure occurs first, followed by dimensional loss due to wear, and finally corrosion. Galling and wear must be the first concerns of the design engineer. Although the general corrosion resistance of NITRONIC 60 is not quite as good as Type 316, it does offer better chloride pitting resistance, stress corrosion cracking resistance and crevice corrosion resistance than Type 316 in laboratory conditions. Corrosion tests are not normally performed with NITRONIC 60 High Strength.
Corrosion Resistance
Nitronic 60's uniform corrosion resistance is better than 304 stainless in most environments. The yield strength of Nitronic 60 is nearly twice that of 304 and 316 stainless steels. Chloride pitting resistance is superior to that of type 316 stainless; Nitronic 60 provides excellent high temperature oxidation resistance and low temperature impact.
Applications using Nitronic 60 are valve stems, seats, and trim, fastening systems, screening, pins, bushings and roller bearings, pump shafts and rings. Other uses include wear plates, rails guides, and bridge pins.
Wear Resistance
This alloy provides a significant lower cost way to fight wear and galling compared to Nickel or Cobalt based alloys.

Nitronic 60 can be hot forged. After forging the workpiece must be solution annealed.
The alloy is difficult to machine, rated at 50% of 304 and 23% of the free cutting carbon steel AISI B1112. Sharp, rigid, carbide tipped tools and well powered machines are recommended, with the use of heavy cuts and slow speeds.
Nitronic 60 is fully austenitic and can not be strengthened by heat treatment. Solution annealing is carried out at 1060°C, followed by water quenching
Nitronic 60 is readily welded by all conventional processes. Autogenous GTAW welds are sound, with wear characteristics approximating to the base metal. GTAW welds in heavy sections are also sound and weld tensile strength is slightly higher than base metal. Wear properties are near but below base metal. Pure argon is used as shielding gas and AWS A5.9 ER 218 filler metal is used. Pre-heating and post heating are not needed.
