Manual Rockwell: hard alloy, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy,malleable castings, mild steel, quenched and tempered steel, annealed steel,bearings steel.
HR-150A manual Rockwell hardness tester is a universal Rockwell hardness tester. It adopts mechanical manual test, no power supply, wide application range, simple operation, good economy and practicability.The body part of the product is formed by a casting process and has undergone a long-term aging treatment. Compared with the jigsaw technology, the long-term use of deformation is extremely small, and can effectively adapt to various harsh environments.
1. Car paint, high-grade paint, strong scratch resistance, and still bright as new after years of use;
2. Manual Rockwell hardness tester, lever loading, reliable and durable, no need to power on, high test efficiency;
3. The dial directly reads the hardness value, and can be equipped with other Rockwell scales;
4. The frictionless spindle is adopted, and the test force has high precision;
5. It adopts integrated casting precision hydraulic buffer, no buffer oil leakage, smooth loading and unloading, no impact, and adjustable speed;
6. Confirms to GB/T230.2, ISO6508-2 and American ASTM E18 standards
7. It is widely used to determine the Rockwell hardness of ferrous metals, non-ferrous metals and non-metallic materials.
8. It is mainly used for the measurement of Rockwell hardness of heat-treated materials such as quenching and quenching and tempering. Such as cemented carbide, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy, malleable castings, mild steel, quenched and tempered steel, annealed steel, bearings and other materials.
