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.
