Machinability and other Processes

The normalized or hot-rolled state of 1045 Carbon steel provides excellent weldability, machinability, high strength, and impact properties. At the same time, the normalized form provides superior weldability.

Because of the low through-hardening capabilities of AISI 1045 steel, it is recommended that only portions of approximately 60 mm in size be used for tempering and through-hardening.


Spindles, gears, rolls, axles, shafts, worms, bolts, ratchets, hydraulic clamps, studs, crankshafts are only a few of the many applications of 1045 Carbon.
