Alloy Steel Rectangle Bar 4140 Annealed

Show full description

Alloy Steel Rectangle Bar 4140 Annealed

The 4140 annealed alloy steel rectangle bar is a versatile medium-carbon steel that has been softened to provide maximum machinability. These flat bars are frequently used for manufacturing gears, slides, and machine bases that require extensive milling before final hardening. It is a staple in the industrial machinery sector due to its high fatigue strength and response to heat treatment. The annealing process ensures a consistent internal structure, reducing the risk of warping during the fabrication of complex parts. Onlinemetals.com provides 4140 annealed bars in various sizes to support your custom engineering and tooling needs.
