2 1-24 Cold Finished & Hot Rolled Bar ProductsCold Finished & Hot Rolled Bar ProductsSteel BarsSteel BarsSteel BarsSteel Bars Steel Metals GuideSteel BarsSteel BarsCold Finished Carbon BarsCold Finished Bars are produced from Special Bar Quality Hot Rolled Bars by cold drawing, turning or grinding or by a combination of these methods. The cross sectional area of the hot Rolled bar is cold reduced, resulting in accurate size, smooth surface, increased mechanical properties and is a general purpose low carbon steel with good case hardening qualities. It is especially suited to cold forming and bending operations. Material is suitable for parts which require cold forming (such as crimping, swaging, or bending). For severe bends, however, stress relieving may be necessary to prevent is a medium carbon steel used extensively in induction hardening applications.

3 This is not normally considered a screw machine steel and is only fair for brazing and welding. However, it can be forged satisfactorily and is the most common shafting steel in the medium carbon is a low carbon, high manganese steel. Machinability is improved over 1018, and case hardening is deep and uniform, supported by a tough ductile is a resulphurized steel with good machinability and surface finish. The product is made much the same way as 12L14 where the lead does not alloy with the steel. Lead is retained in its elemental state and is dispersed within the steel's structure allowing chips to break off easier during is a medium carbon, special quality, manganese steel, with improved machinability and better heat treatment response. Surface hardness is deeper and more uniform than plain carbon is a resulphurized carbon steel containing manganese and sulphur to provide a free-machining steel.

4 It is recommended especially for high-production automatic machine Products and machined parts requiring higher strength and wear resistance than is possible with lower carbon Class B, includes Stressproof , is a medium carbon free machining steel that has been severely cold reduced to improve its mechanical properties. Its inherent strength, without heat treatment, is comparable to heat treated steels of equal hardness. This permits direct use of many parts following the last machining operation, without the necessity of a further hardening treatment. 12L14 is considered to be one of the fastest machining steels currently produced. This has been achieved through the addition and even dispersal of tiny lead particles throughout the bar. C12L14 gives a smooth, machined surface and because of its low friction component allows increased tool life.

5 This grade is recommended for high-speed automatic screw machine parts. 1215 is one of the most popular screw stocks marketed today. C1215 provides good surface finish and brazing is made by various combinations of mechanical working and thermal treatment which can include Niagara LaSalle's " " (elevated temperature drawing) process. This is a high strength steel bar that eliminates heat treating and secondary operations such as cleaning, straightening, secondary machining and inspections. All this, in combination with free machining and high strength, operates to lower end costs. Fatigueproof induction hardens satisfactorily, but should be watched for quench cracks. Fatigueproof is also comparitor or roto and Descriptions Steel Metals GuideSteel BarsSteel Bars* 1045 is available in turned, ground and polished condition.** Stressproof A311 Class B is available in ground and polished condition starting at 3/8".
