Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without destruction under load.
.Performance index analysis of square and rectangular tubes-hardness
Hardness is a measure of the softness and hardness of metal materials. At present, the most commonly used method for measuring hardness in production is the indentation hardness method, which uses an indenter of a certain geometric shape to press into the surface of the metal material being tested under a certain load, and the hardness value is measured based on the degree of indentation.
Commonly used methods include Brinell hardness (B), Rockwell hardness (,,) and Vickers hardness.
