The hardware shrapnel is an elastic component, usually made of stainless steel, copper, iron, and manganese materials. The hardware shrapnel relies mainly on elasticity to control the movement of mechanical parts, converting mechanical energy into deformation energy.

I believe everyone has encountered situations where hardware shrapnel deform or do not rebound when pressed, so what are the common causes of these problems?
1: If the tempering temperature after the hardware shrapnel is formed is too high and for a long time, it will lead to insufficient compressive shrapnel strength.

2: If the hardware shrapnel is not subjected to heat treatment after completion, it will lead to insufficient shrapnel elasticity.

3: Frequent load usage of the shrapnel beyond its bearing limit will result in the loss of elasticity.

4: The structural design of the shrapnel is unreasonable, with uneven wall thickness, leading to inconsistent stress and susceptibility to deformation.

5: When the stress on the shrapnel cross-section exceeds its strength limit, it is prone to fracture failure under the effect of varying stress.
