HAYNES® HR-120® alloy exhibits good resistance to oxidizing environments and can be used at temperatures up to 2100°F (1150°C). The following are comparative static oxidation test results at 1600°F (870°C), 1800°F (980°C), 2000°F (1090°C), and 2100°F (1150°C) for 1008 hours.
Burner rig oxidation tests were conducted by exposing samples of 3/8” x 2.5” x thickness (9mm x 64 mm x thickness), in a rotating holder to the products of combustion of 2 parts No. 1 and 1 part No. 2 fuel burned at a ratio of air to fuel of about 50:1. Gas velocity was about 0.3 mach. Samples were automatically removed from the gas stream every 30 minutes and fan-cooled to near ambient temperature and then reinserted into the flame tunnel.
Amount of metal affected for high‐temperature plate (0.25”) alloys exposed for 360 days (8,640 hours) in flowing air. Cycled once per month.
