What are ways to test the hardness or the quality of manufacturing/heat treatment of the spring?
The problem with a normal hardness testing machine (eg a rockwell hardness testing) is that these are usually used for flat surfaces and will be difficult to make accurate on a round surface such as a wire.
Any deformation or cutting on the finished spring to make a flat surface will not work. The suppliers for the steel wire also cannot supply flat surfaces of the material.
Thanks in advance.
