Alloy Steel 4150, also sold under the name AISI/SAE 4150, is a high-carbon alloy that includes chromium, manganese, and molybdenum. This tough steel alloy offers uniform strength, wear resistance, and great hardness. It is important to note that Alloy Steel 4150 must be heat-treated to be suitable for machining. The weldability of Alloy Steel 4150 is high and can be achieved through most commercial methods. The finest of grain size relates directly with the temperature of forging.
Alloy Steel 4150 is used in the aerospace, defense, oil and gas, and automotive industries for products such as:
- Shafts
- Valves
- Sprockets
- Aerospace parts
- Axles
- Spindles
- Forged gears
