How is Rockwell Hardness Measured ? ASTM Standard Rockwell Hardness Test Method
Brief Introduction:
This instrument is in accordance with the Rockwell measuring principle.it can do the testing of Rockwell hardness directly.It has the feature of easy operation,stable reading,convenient maintenance.This instrument is the new design loading and unloading easy operation all-in-one machine,improve the operation procedure compared to the old products HR-150A.which makes machine more stable,durable,and efficient.
Application:
Ferrous metal,non-ferrous metal,non-metal materials;
Quench,tempering.,etc heat treatment materials;
Tempered steel,annealed steel,quenched steel,surface hardened steel,chill casting,forging,hard alloy steel,aluminum alloy,bearing steel,hardened sheet steel.
Features:
- Accurate data,high testing efficiency.
- Leverage of loading,manual operation,durability and reliability
- Non-friction spindle,high accuracy.
- HRA,HRB,HRC scale can be read directly through dial plate.other Rockwell scale is available.
- Adopt precision oil pressure buffer,loading speed is adjustable.
- Mechanical manual testing process.no needs electric controlling.
- Widely apply to quality monitoring on production site.good working environment adaptability
- 8. The accuracy is in accordance with GB/T230.2,ISO 6508-2 and US ASTM E18.
