Hot rolled square bar: 16mm*16mm-100mm*100mm
Available Heat Treatment
Annealing: AISI 4130 steel can be annealed at 843°C (1550°F) followed by air cooling at 482°C (900°F).
Tempering: 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.
4130 steel alloy is used primarily in the construction of commercial and military aircraft and ground support systems as well as automotive, race cars, off road, hydraulic tools, and machine tool applications. It is an intermediate strength material.
