Brinell Hardness Test Vs Rockwell

The Rockwell B values are superimposed on this table using an approximation from ASTM E140 Table5 which compares Rockwell B and Brinell. Elongation at Break Percentage.

Rockwell Hardness Scales Conversion Chart Chart Organizational Chart

HRA HRB and HRC scales are most widely used.

. The accuracy of the conversion depends on the. Brinell har d ness test is similar to the Rockwell as they both evaluate the metal impression left by an intended object. There are three commonly used HRA HRB and HRC of which HRC is the most widely used.

Portable Brinell TesterMETAL HARDNESS TESTING MADE EASY TEST METAL HARDNESS ANYWHERE ANYTIME The King Portable Brinell Hardness Tester is the most reliable user-friendly and affordable portable Brinell tester and the ONLY portable Brinell tester on the market that is calibrated and certified per ASTM E-10 standards. With an angle of 136 between opposite faces in order to obtain hardness numbers that would be as close as possible to Brinell hardness numbers for the specimen. The application of these 9 rulers covers almost all commonly used metal materials.

It is not used in applications that require high strength or hardness. Rockwell hardness test HR principally used in the USA. Delivers a full 3000 kgf load ASTM E.
