describe:

* brand new and high quality

* Made of high quality material, and practical

Multilayer high elastic spring:

The spring mainly works under dynamic load, that is, under the conditions of shock and vibration, or under the  alternating stress, and uses elastic deformation to absorb shock energy and play a buffering role.

Because the spring often suffers from vibration and works under the of variable stress for a long time, mainly fatigue damage, the spring must have high elasticity and high fatigue resistance and sufficient toughness and plasticity to prevent sudden brittle fracture under the impact force. .

In terms of manufacturability, spring steel should have good hardenability and low overheating, decarburization sensitivity, reduce spring surface roughness, and improve fatigue life
