Application

AISI 1018 is used in bending, crimping and swaging processes,and it is suitably used in applications that do not need high strength of alloy steels and high carbon.AISI 1018 is used to improve drilling, machining, threading and punching processes,and also can be  used to prevent cracking in severe bends.

Typical Applications:

Shafts, Spindles, Pins, Rods, Sprocket assemblies, Axles, Bolts, Fixtures, Mounting plates, Spacers, Machinery parts
