COLD FINISHED CARBON BARS - 1018
1018 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 cracking.
HOT ROLLED CARBON BARS - 1018
1018 is a general purpose low carbon steel with good case hardening qualities. It is especially suited to cold forming and bending operations and has excellent weldability.
HOT ROLLED CARBON BARS - A36
A36 is produced to a 36 ksi min yield point. A mild carbon steel with many uses that works well for fabricating, welding, bending and cold forming.
HOT ROLLED CARBON BARS - Commercial Quality Strip
CQ or Commercial Quality Steel is ordinarily produced from a low carbon steel. Specific chemistry and mechanical properties are not inherit to CQ products.
HOT ROLLED CARBON BARS - 1044 HR
1044 is a medium carbon steel used when greater strength is needed. Has good heat treating properties when induction or flame hardened.
COLD FINISHED CARBON BARS - 1045 CF
1045 is a medium carbon steel used extensively in induction hardening applications. 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 range.
COLD FINISHED CARBON BARS - 1045 Turned Ground & Polished
1045 is a medium carbon steel used extensively in induction hardening applications. 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 range.
HOT ROLLED CARBON BARS - 1045 HR
1045 is a medium carbon steel used extensively in induction hardening applications. This is not normally considered a screw machine steel and is only fair for brazing and welding. 1045 hot rolled can be used for applications requiring more strength and wear resistance than the low carbon mild steels can provide.
COLD FINISHED CARBON BARS - 1117 CF
1117 is a low carbon, high manganese steel. Machinability is improved over 1018, and case hardening is deep and uniform, supported by a tough ductile core.
COLD FINISHED CARBON BARS - 11L17 CF
11L17 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 machining.
HOT ROLLED CARBON BARS - 1117 HR
1117 is a low carbon, high manganese steel. Machinability is improved over 1018 and case hardening is deep and uniform, supported by a tough ductile core. A free machining grade with improved mechanical properties suitable for carburized parts.
COLD FINISHED CARBON BARS - 1141 CF
1141 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 steels.
HOT ROLLED CARBON BARS - 1141 HR
1141 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 steels.
COLD FINISHED CARBON BARS - 1144 CF
1144 is a resulphurized carbon steel containing manganese and sulphur to provide a free-machining steel. 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 steels.
HOT ROLLED CARBON BARS - 1144 HR
1144 is a resulphurized carbon steel containing manganese and sulphur to provide a free-machining steel. 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 steels.
COLD FINISHED CARBON BARS - 12L14 CF
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. This grade is recommended for high-speed automatic screw machine parts.
COLD FINISHED CARBON BARS - 1215 CF
1215 is one of the most popular screw stocks marketed today. C1215 provides good surface finish and brazing properties.
COLD FINISHED CARBON BARS - A-311/Stressproof®
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.
COLD FINISHED CARBON BARS - Fatigueproof®
Fatigueproof® is made by various combinations of mechanical working and thermal treatment which can include Niagara LaSalle's "e.t.d."® (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 tested.
