Rockwell Hardness Test. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload .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). This formula gives an approximate value for the Brinell hardness value, and quality assessment professionals use it to create the conversion tables and charts for instant conversion.
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 .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 and consequently the widest variety of materials and applications (see table below).Rockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method. Here, the indenter makes a residual depth called the indent and it is .

The specified preliminary force is applied
Rockwell Hardness Testing Reference Guide ASTM E18 contains a listing of all regular Rockwell scales and typical materials for which these scales are applicable. Use these tables in selecting the scale that is appropriate for your application. Regular Rockwell Testing. In this test method, the minor (preload) is always 10 kgf. .The Equotip 550 is the most versatile all-in-one solution for portable hardness testing. The Leeb hardness principle is based on the dynamic (rebound) method and is best suited for on-site testing of heavy, large or already installed parts. In combination with the Equotip Portable Rockwell Probe, the Equotip 550 can be 1.5 Units— At the time the Rockwell hardness test was developed, the force levels were specified in units of kilograms-force (kgf) and the indenter ball diameters were specified in units of inches (in.). This standard specifies the units of force and length in the International System of Units (SI); that is, force in Newtons (N) and length in millimeters (mm).It is very safe in hardening as far as reaching the desired hardness. O1 Tool Steel Properties. The density of 01 steel is 7.85 g/cm3 (0.283 lb/in3); Rockwell C hardness is 50 HRC; Ultimate tensile strength 1690 MPa (245 ksi), Yield strength 1500 MPa (218 ksi), based on oil quenched at 800°C, tempered at 425°C.

High Rockwell hardness numbers represent hard materials and low numbers soft materials. d 2 www.wilsoninstruments.com Fundamentals of Rockwell Hardness TestingRockwell hardness test is applied with the carbide balls to test softer materials such as construction steels or brass because if you test soft material with diamond cones, it could cause very deep penetration into the material which will go far outside from the specified depth of 0.2mm. With a carbide ball, the specified reference depth is .The Rockwell hardness testing method fulfilled every requirement. After 100 years, it’s still the best metal strength test method. The Rockwell C scale is also the most precise way to report metal strength used in industrial machine knives. How Rockwell Hardness Gets Measured.
The Rockwell Hardness test is a widely used method to determine the hardness of metallic materials, thanks to its simplicity and quickness. This hardness test is based on indentation and depth of penetration, and it can be performed on various metals, including aluminum, copper alloys, brass, soft steels, and hard carbon steels. .Hardness of Titanium Grade 2.
