Nitronic 60

Nitronic 60®  (UNS S21800) is an austenitic stainless steel that has about twice the yield strength of 304 with better corrosion resistance. The alloy has excellent high temperature oxidation resistance. In addition Nitronic® 60 and has outstanding galling resistance . Nitronic 60 stainless steel provides a significantly lower cost way to fight wear and galling compared with cobalt-bearing and high nickel alloys.  Chloride pitting resistance is superior to Type 316. Room temperatrue yield strength is nearly twice that of Types 304 and 316. 

Characteristics
Corrosion Properties
The corrosion resistance of  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. 

Heat Treatment
Nitronic 60® is non hardenable by heat treatment. 

Applications Potential

 Outstanding galling resistance at both ambient and elevated temperatures makes Nitronic 60 stainless steel a valuable material for valve sterns, seats and trim; fastening systems, including nuts and bolts; screening; chain-drive systems; pins, bushings and roller bearings; and pump components such as wear rings and lobes. Nitronic 60 is the most effective wear and galling resistant alloy for bridge pins and other critical construction applications.

Available Forms 

 

Nitronic 60 stainless steel is available in bar, ingots and forging billets. Other forms available include sheet and strip, castings, extrusions, seamless tubing and plate.

Nitronic® 60, or N-60 is known for its excellent galling resistance, even at elevated temperatures. The additions of 4% silicon and 8% manganese inhibit wear, galling, and fretting. It is commonly used for various fasteners and pins that require strength and resistance to galling. It maintains decent strength up to temperatures of 1800°F and has oxidation resistance similar to that of 309 stainless steel. The general corrosion resistance is between that of 304 and 316 stainless steel.

Austenitic Stainless

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.

Applications Potential

Outstanding galling resistance at both ambient and elevated temperatures makes Nitronic 60 stainless steel a valuable material for valve sterns, seats and trim; fastening systems, including nuts and bolts; screening; chain-drive systems; pins, busings and roller bearings; and pump components such as wear rings and lobes. Nitronic 60 is the most effective wear and galling resistant alloy for bridge pins and other critical construction applications.
