Different Grades

1018 – A low carbon steel with medium manganese content. This alloy has good case hardening properties, fair machinability. Conforms to ASTM A108. 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 A108. Identification color: Red.

12L14 – A low carbon steel with lead added to greatly improve machining properties. Conforms to ASTM A108. Identification color: White

1144 Stress Relieved – This grade of bar has been worked to produce high mechanical properties. The bars are then specially treated to relieve stresses caused by cold working. The steels have high strength, hardness, and wearability usually only associated with heat treated bars. Conforms to ASTM A311. Identification color: Yellow.

4140/4142 – This medium carbon, chromium-molybdenum steel has been annealed and cold drawn, and has a high hardenability. Prior to cold drawing, the material is softened from the mill structure to a pearlite structure. This softening process improves ductility and machinability. Conforms to ASTM A108. Identification color: Gold

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 a sales associate.
