main feature:
Integrating ordinary Rockwell and superficial Rockwell, expanding the scope of application, lever loading, manual operation, accurate and durable, high testing efficiency; simple and easy to operate, low failure rate; direct reading of the dial, HRA, HRB, HRC, HRN , HRT can also be equipped with other Rockwell standards; the accuracy meets GB/T230.2ISO6508-2 and American ASTM E18 standards.
Applications:
Rockwell is used for Rockwell metal of ferrous metals, non-ferrous metals and non-metallic materials; it is suitable for quenching, modulation and other liquid treatment materials and Rockwell hardness of hard alloys; surface Rockwell is used for ferrous metals, alloy steel, hard alloys And surface Rockwell hardness after nitriding, cyaniding, electroplating and other surface treatments.
