Abstract: An air bag explosive container device for use in inflating an air bag upon receipt of a sensor signal that indicates a collision. The container device includes a lower cylinder portion and an upper cap portion, threadedly connected together and enclosing a chamber for an explosive material. The lower cylinder portion and upper cap portion each consist of (a) carbon iron alloy base material and an outer protective oxide coating located thereon thereby providing both high strength and anticorrosion properties, ease of manufacture, and much lower cost of manufacture.
