9.11.2Brinell hardness test An alternative method is theBrinell hardnesstest, which uses a hardened steel (ortungstencarbide) ball indenter with a diameterDof, usually, 10mm. This is applied under a loadPof 500–3000kg applied for 10–30s. The diameter of the circular indentationdis measured in...
Dozens of different hardness tests find use today, including Brinell, Rockwell and Vickers. Each has variants based on the load used to create the indentation. Brinell tests use the largest loads, suiting it for testing thicker test pieces with relatively rough surfaces,...
The methods and procedure of the laboratory tests are also presented. It is also shown there exists a useful correlation between Brinell hardness and the strength properties of the rock.

11.4.2.4.7Brinell Hardness Test Submerged arc-welding procedure qualifications for P-1, P-3, and P-4 group materials should have a hardness not exceeding 225 Brinell in the weld deposit. On production welds for P-5 and P-6 group material, aBrinell hardnesstest should be taken on 10% of...
