Hardness testing of lock hardware stamping parts

Hardness testing of lock hardware stamping parts, the hardware stamping parts we often encounter are also very important to his testing. Now I will mainly introduce his hardness testing to everyone. In fact, for any thing, we are very important to him. The understanding is step by step, from unknown to understanding. The main purpose of the hardness test of the material is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent processing of metal stamping parts, and the processing technology of different types of metal stamping parts. Plates with different hardness levels are required. Hot-rolled steel sheets are usually thicker, and the Brinell hardness tester is generally specified in the steel standard. Rockwell hardness tester is also feasible to detect hot-rolled steel sheets, and the HRB scale can be used. Portable Rockwell hardness tester It is used to test hot-rolled steel plates, which can be tested without sampling, and the operation is very simple. Various cold-rolled steel plates used for the processing of metal stamping parts mainly use Rockwell hardness testers to detect hardness, usually HRB scales, which are harder Use the HRC ruler.
