Learn more about hardness testing basics here. The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and . The corrections vary according to the sample's diameter and hardness and can be as much as six points on the HRC scale and 12.5 points on the HRB scale. The HRC and HRB scales are the most popular Rockwell scales used. HRC uses a diamond indenter with a 150-KG test force and is used mainly for hardened steels.Hardness test methods and hardness conversion tables Introduction. Hardness is a surface property where indentation, scratching or wear is resisted. The higher the hardness the more resistant is the surface, and the more difficult surface operations such as cutting and machining are. . Vickers Hardness (HV) Rockwell (HRB) Rockwell (HRC) UTS .
Converting hardness Rockwell B (HRB) to hardness Rockwell C (HRC) is a usual practice for many designers when specifying the hardness value of a material. This conversion is possible using charts and tables calculated using formulas to get approximate but acceptable values that can be interchanged for the different Rockwell hardness testing scales. Stainless Steel Hardness Test Method Brinell hardness. The Brinell hardness test is a commonly used hardness assessment method suitable for softer materials. It calculates the hardness by the size of the indentation left by a steel ball when it is pressed into the material. It is expressed in HB, and the larger the value, the harder the material.
