4. Charateristics
1215 Fast cutting steel is considered the standard screw stock. Cutting speeds and machining characteristics are excellent. 1215 is a resulphurized and rephosphorized free machining steel, commonly referred to as screw machine stock. 1215 is an improved free machining steel that has replaced the Bessemer B1113 grade years ago. 1215 is especially suited for automatic screw machine operations where the major requirement is exceptional free-machining quality with a smooth, bright finish.
5. Applications
Can also be used for bushings, inserts, hydraulic hose fittings, couplings, studs, pins, etc. Beyond ordinary machining, it will respond well 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 stress.
