Performance Index Analysis Of Special-shaped Tubes

1. Performance index analysis of special-shaped steel pipe - plasticity
Plasticity refers to the ability of a metal material 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 and softness of a metal material. The most commonly used method for determining hardness in production is the indentation hardness method, which is to use a certain geometric indenter to press into the surface of the tested metal material under a certain load, and determine its hardness value according to the℃of indentation.

3. Performance index analysis of special-shaped steel pipes - 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 work under cyclic loads, and under such conditions the parts develop fatigue.

4. Performance index analysis of special-shaped steel pipe - impact toughness
The load acting on the part at a great speed is called the impact load, and the ability of the metal to resist damage under the impact load is called the impact toughness.

5. Performance index analysis of special-shaped steel pipe - strength
Strength refers to the resistance of a metal material to failure (excessive plastic deformation or breakage) under static load. Since the load acts in the form of tensile, compression, bending, shear, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength, etc. There is often a certain relationship between various strengths, and tensile strength is generally used as the most basic strength indicator in use.
