Application of Rockwell Hardness Tester


-Rockwell scale Indenter Preload

               (kgf) Main load

               (kgf) Typical application

Rockwell C Diamond cone with a vertex angle of 120 ° and a vertex curvature radius of 0.2 mm 10 150 Hard material with a hardness between B100 and C70

D 100 requires materials that are slightly lighter than Class C loads. (Light to moderate case hardened steel)

A 60 superalloy, thin steel and shallow case hardened steel

G 1/16 "diameter steel ball 10 150 material is harder than Class B test

B 100 Annealed steel with hardness between B0 and B100.

F 60 bearing metal, annealed brass, copper and sheet metal

K 1/8 "diameter steel ball 10 150 Very soft material (bearing metal and extremely thin material)

E 100
