Alloy Steel Bar

Alloy bars are more commonly used in the hot rolled​ or hot rolled heat treated condition but are available in cold finished. 

Alloy bars are used when increased strength, toughness, wear resistance and fatigue resistance are required. Typical applications would be camshafts, axles, shafts, pistons, gears and bearings.

Hot Rolled Carbon

​1045/1045H, Machines Straightened (ASTM A576/90 Fine Grain)

​Hot Rolled Alloys

​4140-4340 Annealed, Machine Straightened (ASTM A29/29M, A304, A322) 4140-4340 Quenched & Tempered, Machine Straightened, Stress Relieved (ASTM A29/29M, A322, A434 Class BC), 8620 Machine Straightened (ASTM A29/29M, A322


Cold Finished Bar

Cold finished steel bars are generally used for machined parts and shafting. The advantages of cold finished bars are:

  1. Higher Yield & Tensile Strength
  2. Smoother Surface & Closer Tolerances
  3. Improved Straightness
  4. Improved Machinability 

Typical applications for cold finished carbon bars in the 1000 series would be: shafting, conveyors, furniture and display systems. 

The 1100 series would be used for parts requiring extra strength and enhanced machinability. Typical applications would include gears, pinions, rotors and heavy duty threaded fasteners. 

The 1200 series would be used for screw machined parts typically with high speed CNC machines. Typical applications would be screws, nuts, hose couplings, connectors and small shafts.
