Hot, cold, rolled, annealed, quenched and tempered—alloy bars come in many ways. Let’s meet some common grades of alloy bar, segmented by different categories of treatment.

Improved-Machining Alloy Bars

Free machining alloys provide all the benefits of the latest developments in leaded or resulfurized analyses. Improved machining alloys machine as much as 50% faster and increase tool life as much as 300%, with improved finish. In addition, all these alloys develop excellent mechanical properties with heat treatment.

  • 86L20
  • 41L40 annealed
  • 41L40/42/47 quenched and tempered
  • 41L50 annealed
  • 4150 RSCA annealed
  • 4150 RSCA quenched and tempered

CAL-Al Treated Alloy Bars

CAL-AL treated bars are fine-grained, calcium-aluminum treated alloy steel with superior benefits for users of carbide tooling as well as high-speed tooling. Speeds and feeds have been doubled and tool life increased as much as 300%. CAL-AL treated bars deliver their machining benefits without sacrificing mechanical properties.

Low Carbon Alloy Bars – Case Hardening

The ability to develop a hard case supported by a tough, ductile core is characteristic of case hardening alloys – with the exact properties developed, depending on the type of alloy selected and the manner of heat treatment.

Heat Treated Alloy Bars

These alloys have been quenched and tempered so that strength and hardness is already developed, ready for use. Many hot-rolled bars are machine straightened and can be furnished with or without stress relieving. All cold drawn bars are fully stress relieved after drawing so that distortion during machining is held to a minimum.

Medium Carbon Alloy Bars – Annealed

The medium carbon and direct hardening steels in this group offer the right combination of strength, toughness and hardness after oil quenching and tempering – plus machinability. When increased wear resistance is required in localized areas, they can be flame or induction hardened.
