STS Wire
Steel Type Stainless Wire
STS Wire refers to using stainless materials and Cold pressure method among metal forming methods(Cold Heading, Cold Forging: a type of processing method at room temperature). Strict levels of quality are required for the internal(skin tissue, internal defects) and external (dimensions and surface conditions) of the material.
