Product Description Product DescriptionManual Rockwell Hardness Testing Instruments HRA HRB HRC Features:1. The dial will display hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;2. One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance capability and still look bright as new after use many years; Working principle of Rockwell hardness test:The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.Main application:Hardened steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;Product ParametersTechnical parameters:ModelR-150MRockwell scaleHRA,HRB,HRC,HRD,HRE,HRF,HRG,HRH, HRK,HRL,HRM,HRRConversion scaleCheck Conversion tablePreliminary test force10Kg(98N)Total test force60Kg (588N), 100Kg (980N), 150Kg (1471N)Tolerance range:±1.0%Resolution0.5HRHardness value rangeHRA:20~88 HRB:20~100 HRC:20~70 Hardness data readDialLoading methodManualDwell timeManualTest spaceMaximum height :170mm Maximum throat depth:135mmSize / weight Instrument size: 466*238*630mm(L×W×H)/Net Weight: 65kgExecutive standardGB/T230.2 , BSEN 6508, ASTM E18 , ISO 6508 , JJG112Standard Accessory:Standard accessories Rockwell hardness tester host: 1 setDiamond Rockwell indenter:1 pc1.588mm diameter hard alloy steel ball indenter :1 pc, Standard hardness block: 3 pcsLarge testing table: 1 pcMedium testing table: 1 pc V-shaped testing table: 1 pc, 1.588 mm diameter steel ball :5 pcsDust-proof cover: 1 pc, Accessory case :1 pc Operating instruction :1pc Quality certificate :1 pcHardness conversion table:1pc Warranty card :1 pc.Optional accessoriesBlock, IndenterHardness scale, force, Indenter relation:ScaleIndenterPreliminary test force (N)Total test force (N)ApplicationsADiamond indenterconing angle 120°0.2mm radius of top sphere 98588Horniness alloy, cementite steelD 980Thin steel, quenched caseC 1471Quenched steel, thermal refined steel, cast steelFDiameter of steel ball1.588mm(1/16 inch) 588Anneal copper alloy, thin soft steelB 980Soft steel, aluminum alloy, copper alloy, castingG 1471Pearliest iron, copper, nickel, zinc, nickel alloyHDiameter of steel ball3.175mm(1/8 inch) 588 E 980 K 1471 Main ProductsComany Profile & Certificates FAQ
