General Characteristics of AISI 1025

Similar to AISI 1020, AISI 1025 is a low- to medium-carbon alloy appropriate for general engineering and construction applications. Offering good machinability, AISI 1025 can be normalized, hot- and cold-worked, or water quenched and tempered.

Chemical Composition of AISI 1025

• Carbon 0.22-0.28
• Manganese 0.30-0.60
• Phosphorus 0.04 max
• Sulfur 0.050 max
• Silicon 0.15 to 0.30, or:
• 0.10 max
• 0.10-0.20
• 0.20-0.40
• 0.30-0.60
• Iron balance

Heat Treatment of AISI 1025

• Normalize at 1625° to 1700°F (885° to 927°C) before air cooling
• Full anneal at 1575° to 1700°F (857° to 927°C)
• Process anneal after cold working at 1100° to 1225°F (593° to 663°C)
• Harden at 1550° to 1625°F (843° to 885°C) before water quenching
• Can be case hardened

Applications of AISI 1025

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

Machinability of AISI 1025

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

Workability of AISI 1025

• 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
