Features
- The fuselage part of the product is formed by casting process at one time, and has undergone long-term aging treatment. Compared with the jigsaw process, the long-term use deformation is extremely small, and can effectively adapt to various harsh environments;
- Automobile baking paint, high-grade paint quality, strong scratch resistance, still bright as new after many years of use;
- Electric digital surface Rockwell hardness tester, accurate, reliable, durable, high testing efficiency;
- The test force is small, leaving a small indentation, which will not affect the continued use of the test piece;
- Digital display directly reads HRN, HRT scales, and other scales can be selected;
- The rockwell hardness test machine adopts a frictionless spindle, loaded with a lever, and has high test force accuracy;
- The integrated casting precision hydraulic buffer has no leakage of buffer oil, and the loading and unloading is stable, no impact, and the speed is adjustable;
- The accuracy complies with GB/T230.2, ISO6508-2 and American ASTM E18 standards.
Applications
Surface hardened steel, copper, aluminum alloy sheet, strip steel, hard alloy steel, galvanized, chrome-plated, tin-plated, material surface heat treatment and chemical surface treatment of various metal materials.
