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

I believe that many of you have encountered situations where hardware shrapnel deform or do not rebound when pressed, so what are the general causes of such problems?

1. If the tempering temperature of hardware shrapnel after forming is too high and lasts too long, it will lead to insufficient compressive elastic strength.
2. If hardware shrapnel are not subjected to heat treatment after production, it will result in insufficient elasticity of the shrapnel.
3. Frequent load use of the shrapnel, exceeding the limits of the shrapnel’s capacity, will cause the shrapnel to lose its elasticity.
4. If the structural design of the shrapnel is unreasonable, with uneven wall thickness, it will lead to inconsistent stress and is prone to deformation.
5. When the stress on the cross-section of the shrapnel exceeds its strength limit, it is susceptible to fracture failure under varying stress.
