Machinability
The machinability rating of AISI 1040 carbon steel is 60.

Forming
AISI 1040 carbon steel can be formed in the annealed condition.

Welding
AISI 1040 carbon steel can be welded using all welding techniques. It can be pre-heated at 149
to 260°C (300 to 500°F) and post-heated at 594 to 649°C (1100 to 1200°F) due to its high
carbon content.

Heat Treatment
AISI 1040 carbon steel can be heat treated at 844 to 899°C (1550 to 1650°F) followed by
quenching in water and tempering.

Forging
AISI 1040 carbon steel can be forged at 982 to 1260°C (1800 to 2300°F).

Hot Working
AISI 1040 carbon steel can be hot worked from 94 to 483°C (200 to 900°F ).

Cold Working
AISI 1040 carbon steel can be cold worked in the annealed state using conventional methods.

Annealing
AISI 1040 carbon steel can be annealed at temperatures ranging from 872 to 983°C (1600 to
1800°F). It can be then slowly cooled in the furnace. Stress relief annealing process can be

performed at a temperature of about 594°C (1100°F). Normalizing treatment can also be
performed at 899°C (1650°F) followed by cooling slowly.

Tempering
AISI 1040 carbon steel can be tempered at 316 to 705°C (600 to 1300°F) based on the desired
strength.

Hardening
AISI 1040 carbon steel can be hardened by performing cold working process.

Applications
AISI 1040 carbon steel can be used in couplings, crankshafts, and cold

headed parts.
