M2 tool steel is generally suitable for use in applications specified for T1 high speed steel Some applications include drill bits reamers taps gear cutters lathe tools broaches boring tools forming rolls inserts punches milling cutters and end mills Common trade names include Mustang Double Six Vasco M2 REX M2 Micro Melt M2
Rockwell test is based on successfully and repeatably making an indentation in the specimen This requires the material under the indenter to plastically deform The geometry of the plastic deformation created and the force required to make that

Brinell Hardness Number is obtained using a perfectly spherical hardened steel ball of 10 mm pressed against the test surface using a static force of 3000 kg = kiloNewton for at least 10 seconds for steel and measuring the diameters of the indentation left on the surface by means of a graduated low power microscope The result is either
Comments 0 The Rockwell hardness test is used to test the hardness of materials The Rockwell test is usually performed on metals ranging from thin steal all the way to harder metals like Titanium However there are multiple scales to test in and these are identified by by a letter ranging from A V Each scale uses a different indenter and load to perform the test.

Wilson Rockwell hardness test blocks set the standard for the industry and are made from the highest quality material to insure the most uniform and repeatable Rockwell test blocks available A comprehensive variety of scales and hardness test blocks are available to meet the wide ranges and hardness scales associated with Rockwell Brinell Knoop and Vickers testing .
The Rockwell hardness test measures hardness in progressive numbers on different scales corresponding to the size of ball indentor used scale symbols correspond to the loads of 60 and 150 kg Creep and elastic recovery factors are involved in determining the Rockwell hardness Thus Rockwell hardness is not a good measure of wear qualities or

Rockwell hardness is generally chosen for harder plastics such as nylon polycarbonate polystyrene and acetal where the resiliency or creep of the polymer is less likely to affect the results The Ball Indentation Hardness test ISO 2039 1 DIN 53456 is used in Europe much more often than in North America.
