Performance index analysis of spline tube special-shaped tube from China manufacturer:
1. Performance index analysis of splined tube and special——shaped tube - plasticity
Plasticity refers to the ability of metal materials to produce plastic deformation (permanent deformation) without damage under load.
2. Performance index analysis of spline tube special-shaped tube from China manufacturer——hardness
Hardness is a pointer to measure 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 a certain geometric shape of the indenter to press into the surface of the metal material to be tested under a certain load, and the hardness value is determined according to the degree of indentation.
3. Performance Index Analysis of spline tube special-shaped tube from China manufacturer—— 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, under which the parts will fatigue.

4. Performance Index Analysis of spline tube special-shaped tube from China manufacturer——Impact Toughness
The load acting on the machine part at a 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 spline tube special-shaped tube from China manufacturer——strength
Strength refers to the performance of metal materials to resist damage 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, flexural strength, and shear strength. There is often a certain relationship between various strengths, and tensile strength is generally used as the most basic strength indicator in use.
