An apparatus for inflating a vehicle occupant restraint includes an inflator housing which holds gas generating material. The inflator housing includes a combustion cup which is formed from one piece of sheet metal. A diffuser cup, which is also formed from one piece of sheet metal, encloses the combustion cup. A chamber in the combustion cup holds the gas generating material and is closed by a cover. Flanges on the combustion cup, diffuser cup and cover are disposed in overlapping engagement with each other. During formation of the combustion and diffuser cups, the sheet metal is strained hardened to increase the yield strength and ultimate tensile strength of portions of the inflator housing.
