How to test the hardness of sanitary grade stainless steel pipes? How much do you know about the hardness of sanitary grade stainless steel pipes? It is very important to conduct reasonable hardness testing on sanitary grade stainless steel pipes during use. So, how do we use the correct method to conduct hardness testing on sanitary grade stainless steel pipes?
Mechanical property testing methods are mainly divided into two categories, one is Tensile testing, the other is hardness test. The Tensile testing is to take a stainless steel tube as a sample, pull the sample to fracture on the Tensile testing machine, and then measure one or more mechanical properties, usually only tensile strength, yield strength, elongation after fracture and reduction of area. Tensile testing is the basic mechanical property test method of metal materials. Almost all metal materials have Tensile testing as long as there are requirements for mechanical properties. Especially for those materials whose shape is not convenient for hardness test, Tensile testing has become a means of mechanical property testing. The hardness test is to slowly press a hard indenter into the surface of the sample according to the specified conditions, and then test the depth or size of the indentation to determine the size of Hardness. Hardness test is a simple, rapid and easy to implement method in Strength of materials performance test. The hardness test is non-destructive, and there is an approximate conversion relationship between the Hardness value and the tensile strength value. The hardness value of materials can be converted into tensile strength value, which has great practical significance. Because Tensile testing is not easy to test, and it is convenient to convert hardness to strength, more and more people only test Hardness and less test its strength. Especially due to the continuous progress and innovation of hardness tester manufacturing technology, some materials that were previously unable to directly test hardness, such as stainless steel pipes, stainless steel plates, and stainless steel strips, are now possible to directly test hardness. Therefore, when conducting hardness testing on sanitary grade stainless steel pipes, it is necessary to take care of these details to ensure their good performance.
