S7 Tool Steel Hardness
S1 s2 s5 s6 and s7 are the types of shock resisting tool steels.
S7 tool steel hardness. The specific properties of s7 d2 and a2 tool steels which are among the most popular in industrial and manufacturing applications today are discussed in further detail below. M42 tool steel is a molybdenum high speed tool steel with 8 10 cobalt added for increased hardness and hot hardness that is superior to other high speed grades. Aisi s7 tool steel is a shock resistant air hardening steel. What is s7 tool steel.
Two widely used tests are rockwell c and brinell. It offers toughness to withstand chipping and breaking combined with high attainable hardness and good wear resistance. An oversized diameter allows for finishing to your exact requirements. Crucible s7 aisi s7 crucible s7 is a shock resistant air hardening tool steel designed for high impact resistance at relatively high hardness.
In tool steel standard astm a681 shock resisting tool steels are designated as group s steels according to the aisi classification system. Often made into chisels rivets and punches s7 tool steel can handle repeated impact without fracturing. 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. S7 shock resisting tool steel is an air or oil hardening tool steel that is characterized by very high impact toughness.
S7 de carb free is available in rounds flats and squares as well as ground flat stock and drill rod. Hardness tests determine the various properties of a specific metal which includes its resistance to wear toughness and formability. As a result dozens of tool steel types exist. These rods and discs are decarb free for a uniform surface that will consistently accept heat treating.
This results in a sharper cutting edge that lasts longer even when being used to machine high hardness and hard to machine alloys in heavy duty and high production applications. As a result tool steels are suited for use in the shaping of other materials. What is the hardness of s7 tool steel. Rockwell c is measured in the unit hrc which is the measurement used below.
However the aisi sae tool steel code categorizes tool steels based on basic application and material characteristics. S7 shock resisting tool steel.
