Process for the heat treatment of surgical needles by aging |
摘要 |
A method of heat treating and cleaning maraging or precipitation hardening stainless steel surgical needles is disclosed. The method comprises exposing the surgical needles to a partial vacuum at a temperature less than the aging temperature to remove volatile surface contaminants. Then the needles are heat treated in an argon gas environment at a pressure equal to or greater than 1.0 atmosphere.
