Abstract:
A nickel-free stainless steel stent using a stainless steel which does not substantially contain Ni in the stainless steel, has a metal allergy onset-preventing effect, and is excellent in terms of precision workability, strength, and ductility, is provided. The nickel-free stainless steel stent is characterized by using a stainless steel containing, as a chemical composition, from 15 to 30% by mass of Cr, from 0.97 to 2% by mass of Mo, and from 0.5 to 1% by mass of N, with the remainder being Fe, and optionally containing inevitable impurities.
