Hardware stamping parts are also a type of stamping part. Today, let's talk about the inspection of hardware stamping parts!

In order to achieve high surface hardness and wear resistance, many molds and stamp die accessories need to undergo surface heat treatment, such as surface nitriding. For such moldsPeople are very concerned about its surface hardness and hardened layer depth. When testing the hardness of dies of stamped parts that have undergone surface heat treatment, there is a mistaken practice worth correctingCorrect. This is the inappropriate use of a Leeb hardness tester in such situations. This is determined by the principle of the Leeb hardness tester. The three commonly used hardness testers—Brinell, Rockwell, and Vickers—are allUsing the principle of static testing, a hard indenter is slowly pressed into the surface of the specimen, and then the depth or size of the indentation is measured to determine the hardness value. And LiThe Brinell hardness tester uses the principle of dynamic testing.

It involves striking a sphere of specified mass on the surface of a sample at a specified speed, testing the difference between its initial velocity and the rebound velocity to determine the specimen's hardness value.To understand this, just look at how thick the standard hardness block is in the Leeb hardness tester. Obviously, the hardness value it measures is neither the hardness of the nitrided layer, nor is it the hardness of the substrate, but rather the result of their combined effect. Because the thickness of the surface layer of the stamped part varies, different results are inevitable.
