S7 Tool Steel Hardness Range

Its charpy a test that measures the impact strength is over 200 ft lb.

S7 tool steel hardness range.

It is necessary to increase the quench cooling rate between 1400 to 900 f 760 to 482 c by using. Or warm oil to 150 125 f 66 51 c. S7 tool steel properties. Additional material processing and application information for a wide range of tool steel types is available here.

Hudson tool steel shares technical data for s7 shock resisting tool steel including impact toughness. Often made into chisels rivets and punches s7 tool steel can handle repeated impact without fracturing. Also known as drill rod they are ready for turning in a lathe. As an air hardening grade s7 is stable for heat treatment and its combination of high machinability and dimensional stability makes it ideal for a variety of different tool and.

S7 tool steel is a shock resistant grade containing high impact properties. However the aisi sae tool steel code categorizes tool steels based on basic application and material characteristics. The diameter on these rods is precision ground while the straightness is held to a strict tolerance. S7 tool steel is produced and supplied to the machinist or tool maker in the annealed or soft condition.

It offers toughness to withstand chipping and breaking combined with high attainable hardness and good wear resistance. S 7 is typically heat treated and used in the rockwell c hardness range of rc 54 59. Sizes over 2 inches 63 5mm in cross section will not achieve full hardness by cooling in air.
