S7 Steel, Alloy S7 Steel, AISI S7 Steel is used widely for medium-run cold-work tools and dies, for plastic-molding dies, for shear blades, for medium hot-work dies, for master hobs, and for component parts of many products.
It is recommended for both hot and cold shock applications such as rivet sets, chisels, punches, moil points, hot headers and gripper dies. S7 is also suited for short-run dies used in coldforming, blanking, and bending. Other uses include: engraving dies, machined cavities for plasticmolding dies, die-casting dies, shear blades, and master hobs.

|Anneal in a protective atmosphere. Heat rapidly to 1500 to 1550°F and hold at that temperature for one and one-half hours for each inch of greatest thickness. To obtain best machining properties, cool slowly to 1000°F, and then air-cool. This annealing procedure should produce a hardness of Brinell 197 max|
