At present, in many industries such as aviation, aerospace, automotive, and steel in China, end quenching test is the basic method for determining the hardenability of steel.

Standard size end hardened specimen（ Φ 25mm× The test method for measuring the hardenability of steel is to spray water to cool one end face on a specialized equipment after austenitizing (100mm), and then measure the relationship curve between hardness and distance from the water-cooled end along the axis direction.
When using this method for testing, the work is quite complicated: firstly, multiple points need to be drilled to measure the hardness; Secondly, it is necessary to continuously move and record the movement of the loading platform; The third is to draw a curve chart. It often takes a long time to make a sample. In short, to successfully complete this testing task, the hardness tester must meet the following requirements:
1. Requires Rockwell testing method
2. Repeated dot testing
3. Automatically generate reports
4. Easy to operate
The Q150A fully automatic universal hardness testing system imported from Germany from QATM fully meets the above requirements and can quickly solve the hardness testing of end quenching tests,
Practice has proven that using this Q150A hardness tester can greatly improve efficiency and accuracy.
Firstly, the hardness tester host has an automatic indentation function;
Secondly, due to the use of an automatic loading platform, the coordinate values of the points to be measured can be input once before testing, and the instrument will automatically find the set point, with a displacement recovery accuracy of within 2mm;
Thirdly, professional end quenching test fixtures can support up to 8 end quenching specimens;
Fourth, the standard report is automatically generated after the test.
