Low Carbon ground flat stock is a general purpose low carbon steel with good case hardening qualities. With the addition of manganese, Low Carbon ground flat stock is a good choice for carburized parts, since it produces a harder and more uniform case. Low Carbon ground flat stock is a fine grained steel that is readily formed, machined, welded, forged, and has good bending qualities. Supplied ground to close tolerances with a Mattison finish (horizontal spindle) , it is ready to use in its standard prepackaged 24" lengths.
Low Carbon ground flat stock has a wide variety of applications. It is used for parts requiring cold forming, such as crimping, swaging or bending. For severe bends, stress relieving may be necessary to prevent cracking. It is highly suitable for carburized parts, such as jigs, fixtures, cams, patterns. machine parts, non-critical components of tool and die sets, tool holders, etc. It can be used in its supplied annealed state for such applications as backup plates, punch pads, stripper plates, machine pads and machine parts. Low Carbon ground flat stock is suitable for all applications that do not require the greater strength of high carbon and alloy steels
Machinability is rated at 78% of B1112. Average cutting speed 130 ft/min. This grade is easily welded by all welding processes including gas, air, and submerged arc, and the resultant welds and joints are of extremely high quality. Preheat and post-weld heating is generally not necessary.
Low Carbon ground flat stock will respond to any carburizing method and subsequent heat treatments. Case hardening results in a hard case and relatively soft core. Carburize at 1650°-1700°, oil or water quench and temper at 300°. For a hard case and tough core, the following heat treatment is suggested: Carburize at 1650°-1700°F for approximately 8 hours, cool in oven and reheat to 1400°-1450°F. Quench in water and draw at 300°-350°. Carburizing depth typically .060-.070".
