Process for heat treating and tempering surgical needles |
摘要 |
A continuous process for heat treating and cleaning and tempering martensitic stainless steel surgical needles is disclosed. The method comprises exposing the surgical needles to a partial vacuum at a temperature less than the heat treating temperature to remove volatile surface contaminant. Then the needles are heat treated in an argon gas environment at a pressure equal to or greater than 1.0 Torr. Next the temperature of the oven is lowered to temper the needles.
