Latest Patents

Miyawaki holds a patent for a process that produces stainless steels for springs with high strength. The patent, titled "Process for producing stainless steels for spring having a high strength," describes a method involving heat treatment of austenitic stainless steels. The process ensures that the austenite stability index, Md.sub.30, ranges from 0°C to +80°C at a final annealing temperature of 750°C to 1,150°C. The treated steels undergo primary working at temperatures from Md.sub.30 to 500°C with a reduction rate of not less than 20%, followed by secondary working at temperatures lower than Md.sub.30 with a reduction rate of not less than 30%. This innovative method enhances the performance of stainless steel springs significantly.
