Q:How does Nitronic 60 compare to an A286 bolt for high temperature strength?
A: That depends on the strength required and the temperature of your application. A Nitronic 60 bolt is known for its high temperature properties up to 1800F. At these extreme temperatures it can offer good resistance to wear, fretting, and galling; and oxidation resistance comparable to that of 309 stainless. On the other hand it doesn’t offer the high strength of A286. Nitronic 60 offers 95ksi UTS compared to the 120-160ksi UTS of A286. A286 bolts offer excellent high strength, creep resistance and oxidation resistance to a temperature of 1300F – not as high as Nitronic. So it will depend on the temperature range and strength you require.
