PACIFIC 1018 cold finished rounds are stocked in the cold drawn condition through 4" diameter. The turned and polished condition is stocked in popular bearing sizes from 1-15/16" through 6" diameters. 1018 is a low carbon steel which can be readily machined and welded. It can be heat treated by carburizing and case hardening but will not furnace or flame harden because of its low carbon content. Flats and squares are cold drawn to shape and size.
