Applications S7 Standard is suitable for use in applications requiring high impact strength such as shears, punches, blanking dies, chisels, and zinc die casting dies.
The purpose of Heat Treatment, Selection, and Application of Tool Steels is to make the art of heat treating an understandable practice, to remove the mystery that seems to surround tool steel heat treatment, and to provide a rational basis for the intelligent selection of a particular tool steel based on its intended application.
Applications. S7 steel is primarily used for chisels, punches, rivet sets, stamps, screwdrivers and other applications that require high toughness and resistance to shock loads. Also used for hot punching and shearing where some heat resistance is required.
AISI S7 - Chrome-Moly-Shock Resistant Steel. AISI S7 is a shock steel with exceptional impact properties - unnotched Charpy over 200 ft-lb at 400F temper. Since it hardens in air, it is safe and stable in heat treatment. But perhaps the most remarkable characteristic of S7 is its versatility.
used as a tool steel for stamping must be heat treated differently than one used in a cutting tool. Tool steel heat treatment process-es include: material segregation; fixturing; pre-heating; soaking; quenching; and tempering. The following procedures are gen-eral guidelines for tool steel heat treatment. Certain steels require
lAISI S7S7 is a a shock resistant tool steel that combines an easy heat treatment process, a very good toughness, along with a good mach. This grade is typically used for: Backing plates. Blades, shears, punch, chisels. Support plates.
Crucible S7 is a shock resisting tool steel with excellent toughness and high strength, along with low to medium wear resistance. It has been widely used for many years to make chisels and punches which undergo shock loading, and has found increasing use for small plastic molds.
