AISI 4130/ JIS SCM430/ DIN 25CrMo4 FORGED ALLOY STEEL BAR is a low-alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability and machinability.
|Standard||Grade||Chemical composition (%)|
Forged steel round bar: dia100mm-dia1500mm
Forged flat bar: thickness20mm-400mm, width80mm-1000mm
Forged steel block: 100mm*100mm-1000mm*1000mm
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.
