Abstract

1445533 Heat-treating cartridge cases MANUFACTURE DE MACHINES DU HAUTRHIN SA 16 Sept 1974 [9 Oct 1973] 40267/74 Heading C7N [Also in Division F3] Steel cartridge cases having a wall portion 12 and a base portion 14 are heated inductively such that the wall portion 12 is heated above the transformation temperature (i.e. above Ac3) while a portion of the base 14 remains below the transformation temperature, the case being subsequently quenched and annealed. The transition zone 24 between the heated wall portion and the portion of the base where the temperature is below the transformation point is situated within the base.
