Reference Table: Steel hardness conversion chart - all values approximate. Brinell Hardness HB Rockwell HRC Rockwell HRB Vickers HV N/mm²; 800: 72---780: 71It is impossible to define a single conversion method using different hardness test methods. That’s why these standards formulate tables for conversion process, with test load and hardness ranges. Here are the hardness tables and conversion charts for you. . HBW. Tungsten Carbide 10mm ball. 3000kgf. HBS. Steel 10mm, steel nickel.
The Brinell hardness test was developed by Swedish engineer Johan August Brinell in 1900. The Rockwell hardness test was invented in the 20th century by Stanley P. Rockwell, and later refined by Hugh M. Rockwell. The Vickers hardness test, meanwhile, was developed at Vickers Ltd in the United Kingdom in 1921. .
There are a variety of hardness test methods in common use (e.g. Brinell, Knoop, Vickers and Rockwell). . (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.HARDNESS CONVERSION CHART HRA HRB HRC HRD HRE HRF 15-N 30-N 45-N 30-T 3000 kg 500 kg Rockwell Rockwell Superficial Brinell Vickers Shore 61 98 21 40.9 --- --- 69.9 42.3 20.7 81 228 189 243 35 The calculator has two modes — calculate and convert.The calculate mode is helpful if you have the indentation depth and want the Rockwell hardness number for either scale B or C. The convert mode is for converting Rockwell hardness numbers to a different scale like Brinell or Vickers.. The hardness data can not be presented in terms of a universal conversion . The difference between HBS and HBW lies in the type of indenter used. HBS indicates the use of a hardened steel ball as the indenter and is used to determine the Brinell hardness of materials with a value less than 450, such as mild steel, gray cast iron, and non-ferrous metals. HBW, on the other hand, refers to the use of a hard alloy ball as the indenter .

The Rockwell Hardness test also uses a machine to apply a specific load and then measure the depth of the resulting impression. Rockwell hardness number can be represented by HRB. When the material is very thin, lighter loads must be used, resulting in Rockwell 30T. The test measures the hardness by pressing an indentor into the surface of the .Conversion of hardness-to-hardness or hardness-to-tensile-strength values for unalloyed and low-alloy steels and cast iron.

Hardness test.The table below converts Brinell Hardness to Rockwell Hardness scales and vice versa, then compares those to the approximate tensile strength that those scales indicate. Brinell Hardness: . FREE Mill Test Reports Save on your Mill Test Reports and Certs of Conformance. They're always FREE at OnlineMetals.com. Learn More. Knowledge Hub .
While the Rockwell hardness testing scale is prevalent, it is best to consider the material thickness and softness to select the most suitable scale between Rockwell B (HRB) and Rockwell C (HRC). This article compares two types of Rockwell hardness to help you find the most ideal of the two for your hardness testing and conversion needs.Hardness Conversion per ASTM E-140, Strength per ASTM A370, See bottom half of table. Hardness Conversion Table Brinell Hardness HB 10/3000/15 Rockwell Hardness Superficial Hardness Approx Tensile Dia (mm) HB A 60kg B 100kg C 150kg 15T 15kg 30T 30kg 45T 45kg (KSI) 5.30 126 44.5 70.5 -- 83.5 63.5 43.5 61 5.35 123 44 69 -- 83 62.5 42 60 5.40 121 .This results in 30 different Rockwell scales standardized according to ISO 6508 and ASTM E18 (e.g., A, B, C, 30N, 15T) or Rockwell test methods (e.g.: HRA, HRBW, HRC, HR30N, HR15TW), each covering different hardness ranges .
Using charts and formulas helps designers and engineers convert the hardness value they get from one hardness test to the required hardness test value. For instance, converting from a Rockwell hardness test on the C scale (HRC) to a Brinell hardness test value requires using the formula: BHN = 5.970 x (HRC + 104.7).Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of over 12 different test methods.

What is a Hbw To Hrc? HBW to HRC refers to the conversion from Hardness Brinell (HBW) to Hardness Rockwell C (HRC), which are both measurements of hardness in materials.

A nominal 42 HRBW hardness block was used because it had previously been determined that the lower hardness brass would produce the greatest bending among the three available block hardness levels (42 HRBW, 62 HRBW and 82 HRBW). An uncalibrated and untested nominally 25 HRC reference block was chosen for use as the mating steel block. The Brinell hardness tester uses a hardened steel ball (HBS) or cemented carbide ball (HBW) as the indenter, and the test load varies with the ball diameter, ranging from 3000 to 31.25 kgf. (5) Rockwell hardness indentation is very small, and the measured value is localized, so it is necessary to measure the average value at several points.ROCKWELL RB-1A/HT is an analog hardness tester that measures the hardness of metallic materials by the Rockwell C, B, A method according to the standard STN EN ISO 6508. . 1 pc hardness testing plate for HRBW scale; 1 pc hardness testing plate for HRA scale; 1 pc indenter ROCKWELL; 1 pc ball holder ROCKWELL-B; 1 pc ball with diameter ø 1/16"A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels. Hardness comparison table.
