7. Oxidation resistance and corrosion resistance
The alloy has good high-temperature oxidation resistance. The cyclic oxidation test at room temperature-1095℃ (heating at 1095℃ 15 minutes, cooling at room temperature for 5 minutes) proved that the alloy was slightly oxidized, with little weight loss and no peeling, even exceeding Inconel 702 alloy with outstanding oxidation resistance.

craftsmanship
Alloys are easy to cold-work and hot-work. This process is similar to austenitic stainless steel. The initial forging temperature is 1205℃, and the final forging temperature is 980℃ for large forgings and 870℃ for small forgings. The alloy has good weldability. Inert gas metal welding and inert gas tungsten welding can be used. Using alloy or alloy with similar composition as filler, the filler metal should ensure that the weld has the same oxidation resistance as the matrix. If the alloy slowly passes through the temperature range of 540-760℃ during heating or cooling, carbides are easy to precipitate, which is unfavorable to the performance of the alloy. In order to avoid carbide precipitation, it must be cooled quickly after solution treatment.
use
Used as aerospace structural materials, jet engine parts, thermocouple protection tubes, muffle furnaces, burner partitions, heat treatment baskets and fixtures, radiation furnace tubes, etc.
