1018 Cold Rolled Steel Hexagon Bar
1018 cold rolled steel hexagon bars, or keystock, are an excellent candidate for most processing techniques. 1018 cold rolled steel hexagon bars have a smooth dark grey oiled surface with sharp defined edges, and accurate dimensions throughout. 1018 cold roll bars have a higher tensile and yield strength compared to hot rolled bars. 1018 is a low carbon steel with good case hardening qualities. Designed for close tolerances, and commonly used for machining, shafts, gears and sprockets. ASTM A108-07 is the standard specification for steel bar, carbon and alloy, cold-finished.
Most common cold rolled grade. Good strength, good welding & fair machining. Smooth & straight.
