Overview
IPRE G Impact device is a professional hardness testing equipment, Impact energy of 90mJ, Impact mass 20g, using tungsten carbide ball head material, Hardness up to 1600HV, suitable for a variety of metal materials Hardness measurement.
Features
1. Impact energy 90mJ to ensure test accuracy
2. Ball head diameter 5mm, material is tungsten carbide, Hardness, Abrasion Resistance
3. Impact device diameter 30mm, length 255mm, mass 250g, compact and portable design
4. Support the average surface asperity of the specimen to 6.3 μm, adapt to different surface conditions
5. The minimum weight of the specimen is low, starting from 0.5kg, and the applicability is wide
Principle
The impact device is formed by impacting the surface of the specimen with 90mJ energy through the impact body, and the Hardness value is calculated according to the diameter or depth of the Cedar. For example, the Cedar diameter is 1.03mm and the depth is 53μm at Hardness 300HV, and the Cedar diameter is 0.90mm and the depth is 41μm at Hardness 600HV. Fast, non-Destructiveness Hardness detection is achieved.
Applications
Metal hardness of materials testing, industrial quality control, material research and development
Standards
Standard Richter Hardness Block Hardness: 590 +/- 40HLG, 500 +/- 40HLG
Steps
1. Prepare the specimen to ensure that the surface roughness does not exceed 6.3 μm, and the weight and thickness meet the requirements
2. Stabilize the support specimen and select the appropriate fixing method according to the weight range
3. Align the Impact device to the surface of the specimen and apply Impact.
4. Read the Hardness indication and check if it is within the error range
5. Repeatability test to verify
Notice
• The minimum weight of the specimen must be greater than 15kg, or the stable support range of 5-15kg, or 0.5-5 kg range
• The minimum thickness of the specimen is 10mm, and the minimum thickness of the hardened layer is 1.2mm.
• Indication Error is +/- 12 HLG, indication Repeatability is 12 HLG, need to be calibrated regularly
• Avoid testing under asperity or unstable support conditions to prevent data deviation
