Description
ASTM SAE AISI 1045 steel is one of the commonly used medium carbon steels with an average carbon content of 0.45%, medium tensile properties, good strength, toughness and wear resistance. It can be treated by annealing, flame treatment or induction hardening. C1045 is also known as 1045 cold rolled steel (cold worked), and 1045 hot rolled steel is known as 1045 HR. AISI SAE 1045 material is widely used in industrial applications where higher wear resistance and strength are required, typical applications including: Light gears, shafts, axles, spindles, pins, guide rods, connecting rods, bolts, worms, crankshafts, machine components, etc.
