AISI 1144 Free Cut 45 Plate

  • HOT ROLL FINISH

DESCRIPTION

In the as-rolled condition, has physical properties which are equal to the commercial medium carbon plate steels. Based on one inch longitudinal sections, these properties are:

Tensile Strength …………….90-105,000psi

Reduction of Area …………..20-35%

Brinell Hardness ……………156-196

Yield Strength ……………….50-65,000psi

Elongation in 2 inches ………15-25%

ADVANTAGES

  • Free machining no tendency toward tearing
  • Saves machining time
  • Will attain a high luster with a minimum of polishing
  • Is especially suited to flame or induction hardening
  • Uniform results can be produced with standard heat treating methods
  • Free machining characteristics result in longer tool life and reduced frequency of tool grinding Physical and thermal properties can be favorably compared to those of similar steels, C-1045, C-1141 or C-1144
  • Used extensively for short run dies where flamehardening the wearing surfaces and cutting edges is a distinct advantage.
