A stainless steel wire for use in metal rubber, its preparation method, and metal rubber molded parts.

Abstract

This invention belongs to the field of metal rubber technology, and relates to a stainless steel wire for use in metal rubber, its preparation method, and metal rubber molded parts. The preparation method includes: S1. Smelting using an electric arc furnace, an argon-oxygen decarburization furnace, and a ladle refining furnace, and performing manganese-nitrogen alloying during the smelting process, followed by continuous casting to obtain a cast billet; S2. Heating the cast billet and then hot rolling it to obtain wire rod, followed by cooling; S3. Drawing the wire rod, followed by hydrogen bright annealing; repeating the drawing and annealing process until a steel wire of the target size is obtained; S4. Grinding and polishing the surface of the drawn steel wire to obtain stainless steel wire. This invention, through the combination of manganese-nitrogen alloying, repeated drawing and intermediate heat treatment processes, and surface finishing, ensures that the steel wire has high strength and high surface quality, improves the plasticity of the steel wire, and enables it to be ultimately made into metal rubber molded parts with excellent fatigue performance.
