Introduction
1. Standard Overview
GB/T32660.1-2016 "Metallic Material Webster Hardness Test Part 1: Test Method" specifies the test principle, test instrument, test specimen, test procedure, test result processing and test report of metallic material Webster hardness. This standard is applicable to metallic materials with a measurement range equivalent to Rockwell hardness of 53.0 HRC~92.2 HRC, 28.0 HRB~110.0 HRB and 30.2HRF~98.5HRF.
2. Comparison of standard frames
| Standard dimensions | GB/T32660.1-2016 | Scope of application | Main features |
|---|---|---|---|
| Test principle | Indenter insertion method, depth indicates hardness | Applicable to a variety of metal materials | Formula HW = 20 - L/0.0125 |
| Instrument structure | Frame, handle, indenter sleeve assembly | Three types (A, B, C) | Combination of indenter shape and spring coefficient |
| Calibration requirements | GB/T32660.2 standard calibration | Use standard hardness blocks for daily inspection | Allowable error range control |
3. Test principle and instrument structure
Test principle:The Webster hardness is measured by pressing a steel indenter of a specified shape into the surface of the sample under a certain test force, and the depth of indentation is used to represent the hardness of the material. The formula HW = 20 - L/0.0125, where HW is the Webster hardness and L is the depth of the indenter into the sample (unit: mm). The shallower the indentation, the higher the hardness of the material.
Instrument structure:The Webster hardness tester is mainly composed of a frame, an operating handle and an indenter sleeve assembly. The pressure needle sleeve assembly includes a pressure needle, a load spring, an adjustment nut, a pressure needle sleeve, a reset button, a reset spring and a gauge head (see Figure 1). According to the different combinations of the pressure needle geometry and the elastic coefficient of the force spring, the hardness tester is divided into three types: A, B and C.
Relationship between pressure needle shape and material: Type A is a cone, suitable for aluminum alloy; Type B and Type C are both cylinders, used for copper alloy/mild steel and pure copper respectively (see Table 1).
4. Implementation recommendations
- Calibration frequency: The hardness tester should be calibrated regularly in accordance with GB/T32660.2 standard to ensure measurement accuracy.
- Specimen preparation: The specimen thickness is not less than 1mm, the surface is smooth and parallel, and there is no burr or coating interference. It is recommended that the surface roughness Ra is not greater than 1.6.
- Operation specification:The test should be carried out in an environment of 10℃~35℃, ensure that the indenter is perpendicular to the sample surface, quickly apply the test force and read the hardness value (estimated to 0.5HW).
- Data processing:The arithmetic mean of at least 3 test points is taken as the final result, and the numerical rounding is carried out in accordance with GB/T8170.
