Fabrication
and Heat Treatment
Machinability
The
machinability rate of AISI 1075 carbon steel is 50.
Forming
AISI 1075
carbon steel can be formed using conventional techniques.
Welding
AISI 1075
carbon steel can be welded using all welding methods. It is
pre-heated at 260 to 315°C (500 to 600°F) and post-heated at 649 to
788°C (1200 to 1450°F) to prevent cracking.
Heat
Treatment
AISI 1075
carbon steel can be hardened at 899°C (1650°F). It is then quenched
in oil followed by tempering.
Forging
AISI 1075
carbon steel can be forged at 927 to 1204°C (1700 to 2200°F)
followed by annealing.
Hot Working
AISI 1075
carbon steel can be hot worked at 94 to 483°C (200 to 900°F).
Cold Working
Cold working of
AISI 1075 carbon steel is performed using conventional methods in
the annealed condition. It needs more force compared to low carbon
steels to perform this process.
Annealing
Annealing of
AISI 1075 carbon steel can be done at 926°C (1700°F) followed by
slowly cooling in the furnace.
Tempering
AISI 1075
carbon steel is tempered at 371 to 705°C (700 to 1300°F) after
heating and quenching. It is usually used in the hardened condition
of Rockwell C 55.
Hardening
AISI 1075
carbon steel is hardened by cold working, heating, and quenching.
Applications
AISI 1075
carbon steel is mainly used in cutting tools, and springs.
