PACIFIC 1045 cold finished bars are medium carbon steel and have strengths above 1018 but below the heat treated alloy grades. 1045 can be heat treated and is often induction hardened for surface strength and wear resistance. PACIFIC 1045 Cold Finished Bars are offered in two quality conditions:

TURNED & POLISHED offers medium carbon strength at the lowest cost. Manufacturing tolerances are the widest for this condition. It is stocked in popular shafting sizes from 1-15/16" through 6-15/16" diameters.

ARROW-TEN® PRECISION SHAFTING is ground and polished to insure tight diameter tolerances and 16 rms maximum surface finish. ARROW-TEN® has been successfully used in many higher rpm, medium load applications such as shafts, spindles and arbors.
