The hardness test of seamless steel tube can be divided into two methods, one is a tensile test and the other is a hardness test. The following seamless steel tube manufacturers will introduce you in detail:
The seamless steel tube produced is subjected to a tensile test. The tensile testing machine of the sample pulls the sample to the breaking point. In addition, the mechanical properties of the tensile strength or above are usually only measured, and the yield strength, elongation, and bending rate are the same. area. Tensile testing is a test method for metal materials, almost all metal materials, as long as they are required. Mechanical properties provide the basic mechanical properties for tensile testing. In particular, hardness tests and tensile tests of materials that are not easy to form are the only means of testing mechanical properties.
Hardness testing is the process of slowly pressing a rigid indenter hardness tester into the surface of the sample and then measuring the depth or size of the indentation to determine the hardness of the material. Hardness testing is the simplest, quickest, and easiest implemented method of testing the mechanical properties of materials. Nondestructive hardness testing, in terms of hardness versus tensile strength values, is a similar value. The hardness value of the material can be converted into tensile strength, which has great practical significance.
Because the tensile test is not easy to test, and the hardness conversion is very convenient, more and more people only do small hardness tests and only test their own strength. Especially due to the continuous improvement and innovation of the hardness of manufacturing technology, some original hardness can not be directly tested, such as seamless steel tube, stainless steel plate, stainless steel strip, etc., can now be directly tested. Therefore, the hardness test has a tendency to gradually replace the tensile test.
