Main features:

Combines ordinary Rockwell and surface Rockwell into one, expanding the scope of application, lever loading, manual operation, accurate and durable, high Test efficiency; simple and easy, low failure rate; direct dial reading, HRA, HRB, HRC, HRN, HRT can also be selected with other Rockwell standards; accuracy meets GB/T230.2ISO6508-2 and American ASTM E18 standards.

Application range:

Rockwell is used for Rockwell metals of ferrous metals, non-ferrous metals and non-metallic materials; Rockwell hardness of liquid-treated materials such as quenching and modulation and cemented carbide; surface Rockwell is used for surface Rockwell hardness of ferrous metals, alloy steels, cemented carbide and surface treatments such as nitriding, cyaniding and electroplating.
