5. Forging of AISI Steel S7
Preheat 1200°-1300°F. Forge at 2000°-2050°F. Stop at 1700°F and cool slowly.
6. AISI S7 Tool Steel Heat Treatment
Annealing
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.
Stress Relief S7 steel Material: When desirable to relieve the strains of machining, heat slowly to 1050°-1250°F, allow to equalize, then cool in air.
7. Machinability of Tool Steel S7
When S7 steel annealed to Brinell 197 max, steel S7 is rated at 95, as compared to a rating of 100 for a 1.00 pct carbon tool steel.
8. Applications of ASTM A681 S7 Tool Steel
Because of its unusual combination of properties, S7 tool steel is suitable and versatile for a wide range of tool and die applications. AISI S7 Steel can be used for hot and cold shock applications, medium hot-work dies and medium-run cold work tools and dies.
Other uses include: Bull Riveters, Concrete Breakers (Moll Points), Riveting Dies, Powder Metal Dies, Notching Dies, Dowels, Drills, Drill Plates, Hubs, Plastic Mold Dies, Cold Forming Dies, Blanking Dies, Bending Dies, engraving dies, machined cavities for plastic molding dies, die-casting dies, shear blades and Master Hobs.
