Generally speaking, the material of stainless steel coil used by us will produce elastic and plastic strain under the action of flow force, and if the stress is large enough, it will easily lead to the fracture of stainless steel coil. Therefore, strength can be said to be an important factor in determining the ability of coil to resist deformation and fracture, while plasticity represents the total deformation degree of plastic parts at fracture. Therefore, in uniaxial tension, yield strength and tensile strength can be used as strength index, while elongation and surface shrinkage can be used as plasticity index; as for toughness, it is actually the ability to absorb energy in the whole process of plastic deformation and fracture. For stainless steel coils, it can be expressed by the area between plastic deformation and fracture under the true strain curve.
