Nitronic 60

Nitronic 60 is a highly alloyed austenitic stainless steel offering a combination of good mechanical strength (more than double that of 316) and superior corrosion resistance.

Designed originally as material for use in elevated temperatures (up to 1800°F), Nitronic 60 is a wear-resistant alloy offering outstanding galling resistance in both elevated and ambient temperatures and is ideal for any application where galling or seizing is a cause for concern. The material represents a cost-effective solution to combat the effects of wear when compared with nickel and cobalt-based alloys.

The addition of silicon and manganese in the alloying process gives the product its galling / wear-resistant qualities even in the annealed condition. The hardness in the annealed condition is excellent - comparable materials would require additional heat treatment to compete with Nitronic 60 in its annealed state.

Corrosion Resistance

Corrosion resistance is superior to 304, although, like the majority of austenitic stainless steels, Nitronic 60 may suffer stress corrosion cracking in hot chloride ion atmospheres. Resistance to selective attack such as pitting and crevice corrosion is slightly improved when compared to 316 stainless.

Applications in Motorsport

With such outstanding wear characteristics and high-temperature performance, it is not surprising that motorsport components are a beneficiary of this material.

Use in Fasteners

Fasteners produced in Nitronic 60 are capable of repetitive assembly and disassembly before the threads are worn or torn. The fastenings will not corrode easily either, due to the alloys superior corrosion-resistant qualities.

Product Benefits

  • Wear / galling resistant material
  • Good ambient and high-temperature performance
  • Better corrosion resistance than 304
  • Good hardness in the annealed condition
  • Highly suitable for fasteners - can be used in repetitive assembly and disassembly
