Non-Pb TICS Free-Cutting Soft-Magnetic Stainless Steel

By using a base of K-M38 for anti-corrosion, we improved the machinability.


  • We added titanium carbosulfide (Ti4C2S2) as a free-cutting element to improve machinability.
  • By using water-insoluble TICS as a free-cutting element, we achieved superior corrosion resistance (equivalent to SUS316).
  • It can easily be replaced because its magnetic and mechanical properties are equivalent to K-M38
