How to test the hardness of sanitary stainless steel pipes? How much do you know about the hardness of sanitary stainless steel pipes? It is very important to conduct reasonable hardness testing of sanitary stainless steel pipes during use. So how can we use the correct method to test the hardness of sanitary stainless steel pipes?
Mechanical properties testing methods are mainly divided into two categories, one is tensile test and the other is hardness test. The tensile test is to make a stainless steel pipe into a specimen, pull the specimen to break on a tensile testing machine, and then measure one or several mechanical properties, usually only tensile strength, yield strength, elongation after fracture and cross-sectional shrinkage. Tensile test is the basic mechanical properties test method for metal materials. Almost all metal materials, as long as there are requirements for mechanical properties, have tensile tests specified. Especially for materials whose shapes are not convenient for hardness testing, tensile tests become a means of mechanical properties testing. The hardness test is to slowly press a hard indenter into the surface of the specimen under specified conditions, and then test the depth or size of the indentation to determine the hardness of the material. Hardness test is a simple, rapid and easy-to-implement method in material mechanical properties testing. The hardness test 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 the tensile strength value, which has great practical significance. Since the tensile test is not convenient for testing, and it is very convenient to convert from hardness to strength, more and more people only test the hardness of the material and less test its strength. In particular, due to the continuous advancement and innovation of hardness tester manufacturing technology, some materials that could not be directly tested for hardness, such as stainless steel pipes, stainless steel plates and stainless steel strips, can now be directly tested for hardness. Therefore, when testing the hardness of sanitary stainless steel pipes, these details need to be done to ensure their good performance.
