Features

  • Superior Corrosion Resistance

L605 is a cobalt base, austenitic super-alloy with high strength to 1500 degrees F, good oxidation resistance up to 2000 degrees F, and good formability. In addition, L-605 has good resistance to wear and galling. This alloy can be used in high temperature kilns, sections of aircraft (such as hot sections of jet engines and afterburners) as well as industrial furnace applications. L-605 is non-magnetic and has excellent corrosion resistance in the hot corrosive sections in jet engine applications. L-605 has a high chromium content and is therefore resistant to corrosion in a wide degree of applications such as hydrochloric acid and nitric acid.

Higher strength can be achieved in L-605 by work hardening. L-605 is still non-magnetic after being work hardened. L-605 is typically used in the cold worked condition and a decent increase in hardness and strength can be achieved by aging of the cold worked material.

L- 605 is more difficult to machine than other austenitic stainless steels like 302, 304, 321, and 347.
