In former standards HB or HBS were used to refer to measurements made with steel indenters. A square base pyramid shaped diamond is used for testing in the Vickers scale. Tungsten is widely used metal. >> /Rect [71.952 473.97302 297.33401 487.27603] endobj The test provides numerical results to quantify the hardness of a material, which is expressed by theBrinell hardness numberHB. In all scales, a high hardness number represents a hard metal. 1.1 This test method covers the determination of the Brinell hardness of metallic materials by the Brinell indentation hardness principle. >> Conversion Table. << The tests can generally be applied to the finished product without significant damage. /Filter /FlateDecode Hardness Malleable cast iron is white cast iron that has been annealed. 24 0 obj << /Length 10 << WebBrinell Hardness Test (BHN) The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or tungsten ball subjected to a load of 3000 kg. << >> /S /URI xS**T0464R0 ABRDR!9WA? 4 0 obj Rockwell Hardness (HRC, HRB) to Brinell Hardness Carbon dioxide also is used as a refrigerant, in fire extinguishers, for inflating life rafts and life jackets, blasting coal, foaming rubber and plastics, promoting the growth of plants in greenhouses.
