This article examines the hardness testing and tensile test detection of metal materials, and focuses on exploring metal. The problem of data accuracy in the process of material testing has enabled the employees of metal testing platforms to imitate and give inspiration. 1 Analysis of hardness test of metal materials During the hardness test, there are various detection methods. How to accurately apply the implementation facilities of hardness testing is very necessary. In different implementation facilities, different hardness test values will be obtained, which are detailed in various targets. There are indexes such as material elasticity, shape, strength and hardness. Therefore, 20g cold drawing In the process of testing the hardness of seamless pipes, suitable hardness testing methods are particularly necessary. Only accurate and costly data can be used by the human network, and the guiding meaning in the production process can be manifested. 20g cold drawn seamless pipe hardness testing method The hardness testing of stainless steel should consider the mechanical function, which is related to the performance and quality of processing such as deformation, stamping, cutting, etc. with stainless steel as the material.
