Method for rolling and heat treating small diameter stainless steel rod

摘要

A method for rolling and heat treating small diameter stainless steel rod, comprising the following sequence of steps; cooling the rod prior to and during finish rolling to increase its stiffness; passing the rod through a sizing mill to achieve close tolerances; subjecting the rod to additional water cooling to chill its surface and thereby improve its resistance to surface scratching; forming the rod into rings which are received in an offset pattern on an open moving conveyor; subjecting the offset rings moving along the conveyor to a solid solutioning treatment by reheating and water quenching the same; and then air cooling and drying the rings before collecting them into coils.
