Hardware spring sheets are a type of elastic component, usually made of stainless steel, copper, iron, and manganese materials. They mainly rely on elasticity to control the movement of mechanical parts, converting mechanical energy into deformation energy. I believe everyone has encountered situations where the hardware spring sheet becomes deformed or does not rebound when pressed. What are the common causes of these issues?

1. If the tempering temperature of the hardware spring sheet after forming is too high and the time is long, it will result in insufficient compressive strength.
2. If the hardware spring sheet has not undergone heat treatment after production, it will result in inadequate elasticity.
3. Frequent loading and usage of the spring sheet, exceeding its bearing limit, will result in loss of elasticity.
4. If the structural design of the spring sheet is unreasonable and the wall thickness is uneven, it will lead to inconsistent stress and is prone to deformation.
5. When the stress on the cross-section of the spring sheet exceeds its strength limit under variable stress, it can easily cause fracture failure.
