What is the Rockwell Hardness for D2 tool steel?

D-2 is a tool steel that is supplied in the annealed or soft condition. This grade must be hardened after machining . D-2 is heat treated between 1825 to 1875F. After heat treating, the tool steel will attain a hardness of about RC 62-64. However, after hea treating, the steel is very brittle and must be tempered. Below is a list of common temperatures for D2 try this......Tempering °C150200250300350400HRc62/6161/6060/5957/5656/5556/55See the related links for the D-2 tool steel data sheet and an introduction to the heat treating process.


What is the Rockwell hardness of s-7 tool steel?

S7 tool steel is produced and supplied to the machinist or tool maker in the annealed or soft condition. S-7 is typically heat treated and used in the Rockwell C hardness range of RC 54-59. Form more specific information about S-7 tool steel and heat treating, see the related links below.


How do you compare tool steel grades?

Tool steels are compared to each other. They are usually measured by toughness, hardness and wear resistance. The toughness is detemined by an Charpy impact test. The hardness is measured by a Rockwell hardness tester and reported as HRC or RC. The wear resistance is measured by a number of tests that measured the amount of material removed from the original size after a repetitive movement against an abrasive material. These figures are then gathered and presented on a chart. The grades are then compared with one another based on these three properties. See the links below for more information on comparing tool steels.
