HR-45A Manual Superficial Rockwell Hardness Tester is used to test the superficial hardness of ferrous metal,alloy steel,hard alloy and other matellic materials whose surface is processed by means of carburization,nitridation,cladding etc.especially used in the precision measurement on the parallel surface.
Using Scopes:
- Rockwell Hardness Testing of Ferrous Metal,Non-ferrous Metalt and Non-metallic Material.
- Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging parts, hard alloy steel, aluminum alloy,bearing steel, carburized steel sheet, etc.

- A scale: It is suitable for testing the metal more than 70HRC, such as tungsten carbide, hard alloy as well as the hard sheet material and the hardening material on the surface layer.
- B scale: It is suitable for testing non-ferrous metals and alloys, annealing steel or soft or medium hardness of materials.
- C scale: It is suitable for testing the carbon steel, tool steel and alloy steel.
- Mechnical and manual testing mode,easy and simple operation,without electrical power supply;
- High testing efficiency,with high accuracy hydraulic buffer;
- Durable and reliable loading;
- Direct dial readings,with scales of HRN,HRT and other optional superficial scales;
- Quality certified with GB/T230.1/.2 Natioanal Standard,ISO 6508-2,ASTM E18.
