Product Detail
4130 is a structural steel made in the United States. Executive standard: ASTM A29
4130 steel (also known as AISI 4130 and SAE 4130) is a chromium molybdenum low alloy steel with much higher strength and toughness than typical steel grades. In addition, the carbon content of this alloy is reduced while limiting the thickness strength, providing better weld ability than its 4140 steel counterpart. These characteristics make AISI 4130 a popular choice in the aerospace industry for manufacturing commercial and military aircraft components that require high strength and low weight. Examples include gears, piston pins, etc. Other uses of 4130 steel include automotive parts, cutting tools, and drilling and mining machinery.

Fabrication and Heat Treatment
Machinability
4130 steel can be easily machined using conventional methods. However, machining becomes difficult when the hardness of the steel is increased.
Forming
Forming of 4130 steel can be performed in the annealed condition.
Welding
Welding of 4130 steel can be performed by all commercial methods.
Heat Treatment
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
Forging of 4130 steel can be performed at 954 to 1204°C (1750 to 2200°F).
Hot Working
Hot working of 4130 steel can be done at 816 to 1093°C (1500 to 2000°F).
Cold Working
4130 steel can be cold worked using conventional methods.
Annealing
4130 steel can be annealed at 843°C (1550°F) followed by air cooling at 482°C (900°F).
Tempering
Tempering of 4130 steel can be performed at 399 to 566°C (750 to 1050°F), depending on the desired strength level.
Hardening
Hardening of 4130 steel can be done with cold working or heat treatment.
4130 Alloy Cold Rolled Steel Sheets offer good weld ability without compromising steel abrasion and impact resistance. It is commonly used in structural applications, including gears, fasteners, and some aircraft exterior.
Annealed Steel is “softer” than normalized steel and offers higher work ability while normalized steel offers a higher strength tolerance.
4130 Steel has good mach-inability, good weld ability and can be heat treated. Our material is annealed and meets AMS 6350.
