S7 Tool Steel Hardness Before Heat Treat

S7 tool steel is a shock resisting grade with superior impact properties combined with high toughness machinability and size stability during heat treating.

S7 tool steel hardness before heat treat.

S7 shock resisting tool steel is an air or oil hardening tool steel that is characterized by very high impact toughness. S7 tool steel is produced and supplied to the machinist or tool maker in the annealed or soft condition. As a result dozens of tool steel types exist. This process is commonly called interrupted oil quenching.

However the aisi sae tool steel code categorizes tool steels based on basic application and material characteristics. S7 is easy to machine in the annealed condition and can be readily heat treated. S7 shock resisting tool steel. S7 also has medium hot work characteristics making it a versatile tool steel for both cold and warm shock applications as well as plastic molds that require high hardness.

Air hardening and versatile enough for use in both cold and hot work tooling make s7 suitable for a wide range of applications that require shock resistance size stability and. S 7 is typically heat treated and used in the rockwell c hardness range of rc 54 59. The combination of strength and high toughness makes it a candidate for a wide variety of tooling applications. It can be quenched in air exhibiting minimal distortion on hardening.
