Hardness test

Hardness is a pointer to measure the hardness and softness of metal materials. The most commonly used method to determine the hardness of rectangular tubes in production is the indentation hardness method. It uses an indenter with a certain geometry to press into the surface of the tested metal material under a certain load, and tests its hardness value according to the indentation degree.
