Hardness is a pointer to measure the degree of hardness of metal materials. The most commonly used method to determine the hardness of square rectangular tube in production is the pressure hardness method. It is used to press into the surface of the metal material under a certain load with a certain geometric shape of the indenter, and test its hardness value according to the degree of pressure.
