AISI 1015

General Characteristics of AISI 1015

AISI 1015 is a low-carbon steel that offers superior workability and machinability. A versatile engineering and machinery alloy, AISI 1015 is used normalized, hot-rolled, cold-worked or annealed.

Chemical Composition of AISI 1015

  • Carbon 0.13-0.18
  • Manganese 0.30-0.60
  • Phosphorus 0.040-max
  • Sulfur 0.050 max
  • Silicon (optional)
    • 0.10 max
    • 0.10-0.20
    • 0.15-0.30
    • 0.20-0.40
    • 0.30-0.60
  • Iron balance

Heat Treatment of AISI 1015

    • Normalize at 1675° to 1725°F (913° to 941°C) before air cooling
    • Full anneal at 1600° to 1725°F (871° to 941°C) before furnace cooling
    • Process anneal after cold working at 1100° to 1225°F (593° to 663°C)
    • Harden
      • Carburized
      • Not carburized
      • Can be case hardened

Applications of AISI 1015

  • Machinery parts
  • Construction components
    • Trusses
    • Building sections
  • Tool  and die applications
  • Cold-extruded and case-hardened parts

Machinability of AISI 1015

  • Readily machined
    • Annealed
    • Normalized
    • Cold-drawn
    • Quenched, tempered
  • Good surface finish may be compromised from tearing in annealed state

Workability of AISI 1015

  • Hot roll or forge from 1800° to 2300°F (982° to 1260°C)
  • Intermediate annealing required for substantial cold work
  • Fully anneal when further cold work will follow extensive cold work
