1. Performance index analysis of special-shaped steel pipe-plasticity
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.
2. Performance index analysis of special-shaped steel pipe-hardness
Hardness is a measure of the hardness of metal materials. At present, the most commonly used method for determining hardness in production is the indentation hardness method, which uses an indenter of a certain geometric shape to press into the surface of the me联业制衣材料在一定负载下的测试,一个d the hardness value is determined according to the degree of indentation.
3. Performance index analysis of special-shaped steel pipe-fatigue
The strength, plasticity, and hardness discussed above are all indicators of the mechanical properties of metals under static load. In fact, many machine parts are working under cyclic loads, under which conditions the parts will fatigue.
4. Performance index analysis of special-shaped steel pipe-impact toughness
The load acting on the machine at a very high speed is called impact load, and the ability of metal to resist damage under impact load is called impact toughness.
5. Performance index analysis of special-shaped steel pipe-strength
Strength refers to the performance of metal materials to resist damage (excessive plastic deformation or fracture) under static load. Since the load acts in the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, bending strength, and shear strength. There is often a certain connection between various strengths, and tensile strength is generally used as the most basic strength indicator in use.
