Cold Finished Carbon Steel Bars
Cold finished bars are produced by cold drawing oversized hot rolled bars (that have been cleaned to remove scale) through dies to the required size. This process gives cold finished bars a clean surface finish with tighter tolerances and higher mechanical properties than hot rolled steels of comparable chemistry.
1018
A low-carbon steel with medium manganese content. This alloy is easily case hardened and welded, and has a fair machinability. Conforms to ASTM A-108. Identification color: Green.
1045
A medium carbon steel having higher strength than 1018. Responds well to heat treatment. Commonly used for shafts, gears, and bolts. Conforms to ASTM A-108. Identification color: Red
12L14
A low carbon steel with lead added to greatly improve machining properties. Conforms to ASTM A-108. Identification color: White
1144 Stress Relieved
This grade of bar has been severely cold worked to produce high mechanical properties. The bars are then specially treated to relieve the stresses caused by cold working. These steels have the high strength, hardness, and wearability usually only associated with heat treated bars. Conforms toASTMA-311. Identificationcolor:Yellow.
Random Length
Due to the nature of cold finishing. Bars may come in random length (i.e. 12’ could be 10’ to 14’). Normally 11’6” to 12’6”. If you have special requirements please ask inside sales.
