Low Carbon Free Machining Steel Plate

Free Machining Plate is stocked by Alro in low carbon and medium carbon steel. 1144 Modified as well as several Clean Cut grades are available. These plates are typically used to manufacture cams, gears, machine ways, molds, and sprockets.

1144 Modified Steel

1144 Modified offers high strength and hardness and is applicable where resistance to deformation and wear are essential. It may be flame hardened to further enhance surface properties. It is frequently used as an economical replacement for more expensive quenched-and-tempered alloy grades.

About Clean-Cut Products 

The Clean-Cut/LFM 20 families of plate steel were developed for improved machining. Produced by a special calcium treatment and a controlled sulphur process, Clean-Cut steels contain sulfide inclusions which are predominately calcium modified to make them smaller and more uniformly distributed. The result: enhanced machinability.

Alro stocks the following Clean-Cut Products:

  • Clean-Cut 20®
  • LFM 20
  • FM 15®
  • 1119 Modified
