STEEL BARS

CARBON STEEL

Carbon steel types include low, medium and high carbon content steels whose chemical composition is defined in broad ranges. Low-carbon steel has 0.30% or less carbon; medium-carbon steel has 0.30%-0.60%; and high-carbon steel has 0.60%-1.00% carbon content.

1045

CHARACTERISTICS

Appropriate for forging, with good quenching response, but not recommended for case hardening.

APPLICATIONS

Axles, wheel hubs, rocker arms, gears, crankshafts, pins, bolts, shock absorber rods, nuts, and tractor shoes.
