  • Descriptions:
  • Rockwell hardness test is a simple instrument to test the hardness value of hard metals, carburized steels, quenched steels, hard cast irons, mild steels, Al-alloys, Cu-alloys and malleable irons.
  • II. Standard
    According to ISO 6508 and ASTM E18.
  • III. Feature
    1. It measures the depth difference between the primary and testing load and convert the depth difference to the hardness value.
    2. These machines can be operated semi-automatically.
    3. They are essential testing instruments for quality testing section, university and college, research institution and industrial laboratory.
