Our country has produced Rockwell hardness testers with touch screen control, numerical display and curve display, and automatic printing of test data. Rockwell hardness testing, like Brinell and Vickers hardness testing methods, has become one of the three most commonly used hardness testing methods.

What are the characteristics of a Rockwell hardness tester?

1. The Rockwell hardness tester has the same test principle and accuracy as the desktop computer, conforms to the standards GB/T230, ISO6508, and ASTM E110, and has been tested by the Chinese Institute of Metrology, and the error is not more than 1.5HR. 2. When using the Rockwell hardness tester, the test is fast, simple, and non-destructive. 3. Drum reading mechanism like a micrometer, convenient reading, good repeatability, and high precision. 4. The Rockwell hardness tester is equipped with a magnifying glass with light to ensure convenient reading when used in a dark place in the workshop. 5. Rockwell hardness tester can test flat workpieces and curved workpieces with curvature from Φ50mm to infinity. 6. Rockwell hardness tester can be used to accurately test steel plates, steel pipes, shafts, molds, large forgings, and various large and medium-sized heat-treated parts, surface hardening, and parts on assembly equipment, especially suitable for testing welds and heat-affected zones The hardness. 7. It is used for production inspection and acceptance inspection and can replace the Leeb hardness tester with low precision. 8. Traceable standard hardness block. 9. The indenter is qualified by the standard Rockwell hardness tester. 10. The dynamometer used to verify the test force can be traced to the national secondary reference.

What are the applications of Rockwell hardness tester?

The Rockwell hardness test uses 3 types of indenters and 6 types of test forces. There are 15 scales to choose from according to the material, hardness range, and size of the metal material. It can test almost all common metal materials from very soft to very hard. The application range is very broad. Rockwell hardness tester has been widely used in industrial production, and it has become the main means of inspecting product quality and determining reasonable processing technology. It can test various ferrous and non-ferrous metals and test the hardness of hardened steel, tempered steel, annealed steel, surface hardened steel, plates of various thicknesses, cemented carbide materials, powder metallurgy materials, and thermal spray coatings. The surface Rockwell hardness tester is used to test the hardness of sheet metals, thin-walled pipes, surface hardened steels, and small parts. Rockwell hardness tester can be used for surface hardened steel, quenched and tempered steel, annealed steel, chilled castings, malleable castings, hard alloy steel, aluminum alloy, bearing steel, hardened thin steel plate, etc.

EBPU ELECTROMECHANICAL EQUIPMENT (ZHEJIANG) CO., LTD is a very professional company and has been engaged in the production of Rockwell hardness testers for more than ten years. After years of continuous accumulation and precipitation, the company’s products have been sold in more than 50 countries and regions.
