Test Standards of TT-DRW-S Series Superficial Rockwell Hardness Tester
ISO 6508，ASTM E-18，JIS Z2245，GB/T 230.2
Application of TT-DRW-S Series Superficial Rockwell Hardness Tester
It is suitable to determine the rockwell hardness of ferrous, non-ferrous metals and non-metal materials. Widely used for heat treatment materials, such as quenching, hardening and tempering, etc for materials like hard alloy, carburized steel, hardened steel, surface hardened steel, hard cast steel, aluminum alloy, copper alloy, malleable castings, mild steel, tempered steel, annealed steel, bearings and other materials
Features of TT-DRW-S Series Superficial Rockwell Hardness Tester
