Hengshui acoustic test tube manufacturer's spot hardness testing performance
The tensile test is to make the Hengshui acoustic test tube manufacturer's spot manufacturer into a sample. The sample is stretched to fracture on a tensile testing machine, and then one or several mechanical properties are measured, usually only tensile strength, yield strength, elongation after fracture and shrinkage of area.
Tensile testing is the most basic mechanical property testing method for metal materials. Almost all metal materials require tensile testing as long as they have requirements for mechanical properties. Especially for those materials whose shape is inconvenient for hardness testing, tensile testing has become the only means of testing mechanical properties.
The hardness testing of Hengshui acoustic test tube manufacturer’s spot manufacturers should take into account its mechanical properties, which is related to the performance and quality of deformation, stamping, cutting and other processing using stainless steel as raw material. . Therefore, all Hengshui acoustic test tube manufacturers must conduct mechanical property testing. Mechanical property testing methods are mainly divided into two categories, one is tensile test and the other is hardness test.
Most of the national standards for stainless steel materials stipulate both tensile testing and hardness testing. For those materials that are not convenient for hardness testing, for example, Hengshui acoustic testing pipe manufacturer only specifies tensile testing. In stainless steel standards, three hardness test methods, namely Bu, Luo and Wei, are generally stipulated to measure the HB, HRB (or HRC) and HV hardness values. It is stipulated that only one of the three hardness values can be measured.
In particular, the company's latest developed portable surface Rockwell hardness tester and Hengshui acoustic testing tube manufacturer spot manufacturer pipe Rockwell hardness tester can test stainless steel plates and stainless steel strips as thin as 0.05mm, as well as stainless steel strips as thin as 0.05mm. The ￠4.8mm Hengshui acoustic testing tube manufacturer's spot manufacturer conducts fast and accurate hardness testing. The Hengshui acoustic testing tube manufacturer's spot manufacturer makes it possible to solve problems that were difficult to solve in the country in the past.
The hardness test is to slowly press a hard indenter into the surface of the sample according to specified conditions, and then test the depth or size of the indentation to determine the hardness of the material. Hardness test is the simplest, fastest and easiest to implement method in material mechanical property testing. The hardness test of Hengshui Acoustic Testing Pipe Manufacturer's spot manufacturer is non-destructive, and there is an approximate conversion relationship between the material hardness value and the tensile strength value. The hardness value of the material can be converted into a tensile strength value, which is of great practical significance.
Since Hengshui Acoustic Testing Pipe Manufacturer's spot manufacturer tensile test is not convenient to test, and it is convenient to convert from hardness to strength, more and more people only test the hardness of the material and less often test its strength. Especially due to the continuous advancement and innovation of hardness tester manufacturing technology, it is now possible to directly test the hardness of some materials that could not be directly tested for hardness, such as Hengshui acoustic test tube manufacturers, stainless steel plates and stainless steel strips. Therefore, there is a trend that hardness testing will gradually replace tensile testing.
