Color Marking
1215 are resulphurized and rephosphorized free machining steels, commonly referred to as Screw Stock. They are improved free-cutting steels that have replaced the Bessemer B-1113 grade. They are especially suited for automatic screw machine operations where the major requirement is exceptional free-cutting quality with a good finish.

Applications
|
N/A This Screw Stock was developed for manufacturing numerous parts requiring considerable machining, close finish tolerances, and a bright smooth finish. Beyond ordinary machining, it will respond to roll threading, nibbing, and some minor bending without cracking. It is not recommended for forming, ordinary bending, or upsetting, nor for parts subject to severe fatigue stresses. |
