SHRS-450M Rockwell Hardness Tester
Feature:
SHRS-450M Superficial Rockwell hardness tester is a popularly-used hardness testing instrument to measure the superficial Rockwell hardness of the materials. No need for power supply, the speed of the test force loading is regulated by the buffer and the test force is regulated by the load-change hand wheel. It has easy operation and stable performance, therefore it is widely used.
Application:
Suitable for quenched steel, tempered steel, annealed steel, cold and hard casting, malleable cast iron, hard alloy steel, aluminum alloy, copper alloy, bearing steel etc.
Standard: ISO 6508，ASTM E-18，JIS Z2245，GB/T 230.2
