SAE 7724 Heat Treatments


  • The product shall be supplied in the as-sintered condition unless the product is cold rolled after the final sintering operation, in which case the product shall be stress relieved by heating in a dry, inert or reducing atmosphere to 2100°F ± 25 (1150°C ± 15), holding at heat for not more than 30 min., and cooling at a rate equivalent to air cool or faster.
