AISI S7 Shock-Resisting Tool steel round bar Elongation

S7 Shock-Resisting Tool Steel is an air or oil hardening tool steel that is characterized by very high impact toughness. The combination of strength and high toughness makes AISI S7 Shock-Resisting Tool steel round bar a candidate for a wide variety of tooling applications. It can be used successfully for both cold and hot work applications. Also suitable for hot work tools where the operating temperature does not exceed 1000°F (538°C).

For plastic injection molds, AISI S7 Shock-Resisting Tool steel round bar is available as a remelted, mold-quality product. The remelting process minimizes the number and sizes of nonmetallic inclusions in the steel, and thereby enhances the polishability for critical cavity, insert, and other tooling surfaces.
