Fabrication and Heat Treatment
Machinability - AISI 4130 steel can be easily machined using conventional methods. However, machining becomes difficult when the hardness of the steel is increased.
Forming of AISI 4130 steel can be performed in the annealed condition.
● Welding of AISI 4130 steel can be performed by all commercial methods.
● Heat Treatment - AISI 4130 steel is heated at 871°C (1600°F) and then quenched in oil. This steel is usually heat-treated at temperatures ranging from 899 to 927°C (1650 to 1700°F).
● Forging of AISI 4130 steel can be performed at 954 to 1204°C (1750 to 2200°F).
● Hot working of AISI 4130 steel can be done at 816 to 1093°C (1500 to 2000°F).
● AISI 4130 steel can be cold worked using conventional methods.
● AISI 4130 steel can be annealed at 843°C (1550°F) followed by air cooling at 482°C (900°F).
● Tempering of AISI 4130 steel can be performed at 399 to 566°C (750 to 1050°F), depending on the desired strength level.
● Hardening of AISI 4130 steel can be done with cold working or heat treatment.
Some of the major applications of AISI 4130 alloy steel are in aircraft engine mounts and welded tubing.
