    摘要： Steel with high strength and good formability is produced with compositions and methods for forming austenitic and martensitic microstructure in the steel. Carbon, manganese, molybdenum, nickel copper and chromium may promote the formation of room temperature stable (or meta-stable) austenite by mechanisms such as lowering transformation temperatures for non-martensitic constituents, and/or increasing the hardenability of steel. Thermal cycles utilizing a rapid cooling below a martensite start temperature followed by reheating may promote formation of room temperature stable austenite by permitting diffusion of carbon into austenite from martensite.

    摘要： An austenitic stainless steel ammunition cartridge (12) includes an outer region (16) and a base, wherein the outer region (16) is about 50% - 80% of the thickness of the base, which serves to minimize the sidewall ironing required to form the cartridge. The cartridge blank (10) can be formed by spin forming, compression forming, grinding, or a combination thereof. Tooling (76) to form the blank (10) can include at least a pair of blocks (80) and inserts (78), at least one insert defining a centrally positioned aperture (82).
