Nitronic 60 Bolts with World Wide
Lightning Bolt is renown through the fastener industry as a provider
of exotic alloy fasteners and bolting. One such alloy is Nitronic
60, which 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
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
Fastener galling - capable of frequent assembly and disassembly,
allowing more use of the fastener before the threads are torn up,
also helps to eliminate corroded or frozen fasteners.
As experts in the fastener industry, Lightning Bolt is a name you
can trust for exotic and hard to find bolting. If the job calls for
Nitronic 60 fasteners, call Lightning Bolt.
