Size 2 13/16, 1215-Cold Finished Carbon Steels-Cold Drawn or Ground and Polished Rounds On Fay Industries

(SCREW MACHINE STOCK) ASTM A108 - UNS G12130, G12150
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.

Mechanical Properties

N/A The following are average values for 1" round and may be considered as representative:
Tensile Strength - 87,500 psi
Yield Strength - 75,000 psi
Elongation in 2" - 15%
Reduction of Area - 42%
Brinell Hardness - 187

Machinability

N/A Machinability rating is 136%, based on 1212 as 100%. Average surface cutting speed is 225 feet per minute.

Weldability

N/A Due to their very high sulphur, these grades are not considered as weldable.

Hardening

N/A Although this analysis will respond to conventional treatments, it is not considered a case-hardening steel. Better results can be obtained from 1117 or 1018.
