Applicable Materials

Steel & Cast Steel, Alloy Tool Steel, Stainless Steel, Grey Cast Iron, Ductile Iron, Cast Aluminium Alloy, Copper-Zinc Alloy (Brass), Copper-Tin Alloy (Bronze), Pure Copper, Forged Steel.

Applications

1. It is suitable for on-site hardness testing of heavy workpieces, mold cavities, workpieces with very narrow experimental space, bearings and other parts, large parts and non-detachable parts

2. Failure analysis of pressure vessels, turbine-generator sets and their equipment, as well as material differentiation of metal material warehouses

3. The hardness testing of products in the process of mass production can meet the testing requirements with a set of general standards

4. For hardness testing of annealing, tempering, quenching and other heat treatments, it is necessary to pay attention to the thickness of the hardened layer when selecting the model, and if the hardened layer is too thin, it is necessary to choose a C-type impact device

5. When testing the hardness of the bearing, it is necessary to pay attention to the bearing diameter, if the diameter is too small, the special-shaped support ring needs to be selected

6. When the gear hardness is tested, if the gear is too small, the DL impact device needs to be selected

7. When inspecting castings, if it is difficult to perform the finish, it is necessary to choose the G-type impact device.

Test Scope

Note: When using the Leeb Hardness Tester to measure, the measured workpiece needs to be suitable for the corresponding test conditions, mainly three requirements: the weight of the workpiece is not less than 2KG, the small thickness is not less than 10mm, the surface roughness is not more than 1.6um, and it needs to be firmly supported or densely coupled when it is not suitable for the above conditions!

Indication error and repeatability

The Leeb Hardness Tester meets the standard

1. GB/T 17394.1-2014 "Hardness test on metallic materials – Part 1: Test methods"

2. GB/T 17394.2-2012 "Hardness test on metal materials – Part 2: Inspection and calibration of Hardness Tester"

3. GB/T 17394.3-2012 "Hardness test on metal materials – Part 4: Calibration of standard hardness blocks"

4. GB/T 17394.4-2014 "Hardness test on metallic materials – Part 4: Standard value conversion table"

5. The design is based on the standard: "Technical Conditions for Leeb Hardness Tester" JB/T 9378-2001

Requirements for the surface of the test specimen

The condition of the specimen surface should meet the relevant requirements in the test scope table.

• The surface temperature of the sample should not be too high and should be less than 120°C.

• The surface roughness of the specimen should not be too large, otherwise it will cause measurement errors. The surface of the specimen is exposed to metallic luster, and is flat, smooth, and free of oil.

•  Specimen weight requirements: for heavy specimens greater than 5kg, no support is required, and specimens weighing 2-5kg, specimens with overhangs and thin-walled specimens should be supported by objects during testing to avoid deformation, deformation and movement of specimens caused by impact. For medium-sized specimens, place them on a flat, firm plane, and the specimen is placed smoothly without shaking.

• Curved sample: The test surface of the specimen is flat. When the radius of curvature R of the measured surface is less than 30mm (D, DC, C, DL type impact device) and less than 50mm (G type impact device), small support rings or special-shaped support rings should be used for testing.

• The specimen should have the corresponding thickness, and the small thickness of the specimen should conform to the provisions of the impact device table.

• For specimens with a case-hardened layer, the depth of the hardened layer should be in accordance with the table of impact devices.

• coupling

  1) For light specimens, it needs to be tightly coupled with a strong supporting body, the two coupling surfaces need to be flat and smooth, the amount of couplant should not be too much, and the test direction should be perpendicular to the coupling plane;

  2) When the specimen is a large-area plate, long rod or bent piece, even if the weight and thickness are large, it may still cause deformation and instability of the specimen, resulting in inaccurate test values, so it should be firmly fixed or supported on the back of the test point.

• The specimen itself should be less than 30 gauss.
