Stressproof Ground & Polished 1144 Steel Shaft G&P


stressproof_1144_ground_polished_g&p

Stressproof 1144 ground and polished shaft is a medium carbon, resulfurized steel with added sulfur to achieve a free machining grade with high strength. Stressproof has been cold worked to result in higher tensile properties. Further heat treatment, case hardening etc is not necessary as Stressproof has a hardness similar to that of a heat treated grade. These bars are stress relieved to reduce warpage during machining. The result is a product that extends tool life, resists stress, warpage and distortion, with exceptional surface finish. Uses include: pinions, gears, shafts, mandrels, racks, boring bars, bushings, collets, pins, arbors, and spindles.

Stressproof is a registered trademark of LaSalle Steel Co.
