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.

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

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

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

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.
