WebFormula B – Convert HRB into HB The following two conversion tables are from the standard ASTM A370. Table A is the comparison between Rockwell C hardness, Brinell hardness, Vickers hardness and tensile strength (Rm). Table B is a comparison between HRB, BH, HV and Rm. Table A – HRC to HB, HV, Rm Table B – HRB to HB, HV, Rm Web布氏硬度 (Brinell Hardness) (HB)又稱壓球硬度,是用壹指定直徑 (D mm)的硬化鋼球加以指定之重量 (P kg)以油壓機或槓桿在材料表面成球狀凹面積 (mm2)減去負重。 布氏硬度能試驗大面積的平均硬度,適合於測定正常化 (Normalized)或退火 (Annealed)材料。 硬度值越大,硬度即越高。 洛氏硬度 (Rockwell) (硬度記號HR) 1919年由美國的Stanly.P.Rockwell … WebA useful conversion used extensively in applications involving H 2 S is that 22 HRC (Rockwell C) is equivalent to 248 HV (Vickers), which is often rounded to 250 HV. An earlier standard, BS 860:1967 [3], which has been superseded by BS EN ISO 18265:2003 gives the following equation for hardness conversion between Brinell and Vickers scales.
