This document provides specifications for steel materials used by Sandvik Mining and Construction (SMC). It defines SMC's steel marking system and the standards that steel designations adhere to. The SMC system uses marks like S355K2+N to indicate steel type, quality level, and intended applications.

S7 tool steel belongs to the shock-resisting tool steels classification, designated as group S. This article provides chemical composition, mechanical properties and alternative designations of S7 tool steel.

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 it a candidate for a wide variety of tooling applications. It can be used successfully for …

AISI S7 tool steel is a Shock-Resisting Steel with the highest hardenability and elevated temperature softening resistance of the S-series steels. Due to these properties, S7 material is …

S7 tool steel is a versatile formulation suitable for both cold and hot work service. It has a relatively low carbon concentration compared to D2 and A2 steels (0.45 – 0.55%) and significantly less chromium (3.00 – 3.50%). It features excellent impact and shock resistance and decent resistance to softening at high temperatures.

Tool Steel S7 is a shock resisting tool steel with excellent toughness, high strength and medium wear resistance.
