Fabrication and Heat Treatment
The machinability rate of AISI 1095 carbon steel is 45.
AISI 1095 carbon steel can be formed using conventional techniques. It needs more force that that of the low carbon steels to perform this process.
AISI 1095 carbon steel can be welded using all welding techniques. It is pre-heated at 260 to 315°C (500 to 600°F) and post-heated at 648 to 788°C (1200 to 1450°F)
AISI 1095 carbon steel can be hardened at 899°C (1650°F). It is then quenched in oil followed by tempering. The cutting edge of cutting tools can be hardened by heating and quenching in order to maintain the toughness of the steel.
AISI 1095 carbon steel can be forged at 955 to 1177°C (1750 to 2150°F). Before performing this process, it is annealed at (1650°F) and slowly cooled in order to homogenize the steel.
AISI 1095 carbon steel can be hot worked at 94 to 483°C (200 to 900°F)
Cold working of AISI 1095 carbon steel needs greater force than that of the low carbon steels.
AISI 1095 carbon steel can be annealed at 899°C (1650°F) followed by slowly cooling in the furnace.
AISI 1095 carbon steel can be tempered at 372 to 705°C (700 to 1300°F). It has Rockwell C 55 hardness.
AISI 1095 carbon steel can be hardened by cold working or heat treatment.
AISI 1095 carbon steel can be used in springs or cutting tools, which requires sharp cutting edges such as grass or grain cutting tools.
