Brinell hardness test

Brinell is best known today for the Brinell hardness test, which he proposed in 1900.

An advantage of the Meyer test is that it is less sensitive to the applied load, especially compared to the Brinell hardness test.

Brinell hardness test (HB)

Cementite is very hard and brittle; its hardness is about 640 by the Brinell hardness test, whereas ferrite is only 200.

Brinell is noted as the creator of a method for quantifying the surface hardness of materials, now known as the Brinell hardness test.

The Brinell hardness test, invented in Sweden, was developed earlier-in 1900-but it was slow, not useful on fully hardened steel, and left too large an impression to be considered nondestructive.
