Nitronic 60

Additional information

UNS Number

S21800

Description

Nitronic 60 is a nitrogen strengthened austenitic stainless steel, with outstanding strength and resistance to wear and galling. It has corrosion resistance better than 304, and pitting resistance better than 316. It is also available in bar as a high strength version, Nitronic 60 HS.

Nitronic 60 provides a significantly lower cost solution to wear and galling problems than cobalt bearing and high nickel alloys. It is a high strength austenitic stainless steel strengthened by nitrogen. It differs from more familiar austenitic stainless steels in containing 8% manganese and 4% silicon. The alloy has better uniform corrosion resistance than type 304 in most media. The chloride pitting resistance is superior to type 316, with room temperature yield strength nearly twice that of 304 and 316.

In addition Nitronic 60 has excellent high temperature oxidation resistance and good low temperature impact resistance.

Application

Nitronic 60 can be used in a variety of applications including:

  • Fasteners
  • Marine hardware
  • Boat shafting
  • Pumps and valves
  • Bushings and roller bearings
  • Aerospace applications
