Fabrication
and Heat Treatment
Machinability
The
machinability rating of AISI 1030 carbon steel is 70.
Forming
The formability
of AISI 1030 carbon steel in the annealed condition is good.
Welding
AISI 1030
carbon steel can be welded by all welding methods. It is advisable
to pre-heat the heavy sections of this steel at 149 to 260°C (300 to
500°F) and then post-heat at 593 to 649°C (1100 to 1200°F) for
welding.
Heat
Treatment
AISI 1030
carbon steel is heat treated at 816 to 871°C (1500 to 1600°F) and
quenched in water. This process is followed by a tempering
treatment.
Forging
AISI 1030
carbon steel is forged at 982 to 1260°C (1800 to 2300°F).
Hot Working
Hot working of
AISI 1030 carbon steel is performed at 93 to 482°C (200 to 900°F).
Cold Working
In the annealed
condition, cold working of AISI 1030 steel may be performed by
conventional methods. After annealing, a full or stress relief
anneal may be required.
Annealing
Annealing of
AISI 1030 carbon steel is carried out at 871 to 982°C (1600 to
1800°F) and then slow cooled in the furnace. Stress relief annealing
may be carried out at 538°C (1000°F).
Hardening
AISI 1030
carbon steel is hardened by heat treatment or cold working.
Applications
AISI 1030
carbon steel is suitable for manufacturing machinery parts.
