Nitronic® 60
(UNS S21800)

Nitronic® 60 (UNS S21800) is a wear & galling resistant material.

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.

Capabilities:

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 high and ambient temperatures. It 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. Adding silicon and manganese in the alloying process gives the product its galling / wear-resistant qualities even after annealing. The hardness in the annealed condition is excellent - comparable materials would require additional heat treatment to compete with Nitronic® 60 in its annealed state.

Excellent Performance:

Corrosion resistance is superior and better than 304, although, like most austenitic stainless steels, Nitronic® 60 may suffer stress corrosion cracking in hot chloride ion atmospheres. Resistance to selective attacks such as pitting and crevice corrosion is slightly improved compared to 316 stainless.

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 due to the alloy's superior corrosion-resistant qualities.

Applications in Motorsport:

With such outstanding wear characteristics and high-temperature performance, it is not surprising that motorsport components benefit from using this material. Applications include internal combustion valves, valve stems and fasteners.
