4140 forged steel
4140 forged steel
Our AISI 4140 forged steel is a low alloy steel forging containing chromium, molybdenum, and manganese. 4140 forged steel widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance.
4140 forged steel properties
It contains chromium and molybdenum, which provide excellent wear resistance and durability. Additionally, 4140 steel offers good machinability and weldability, making it easy to work with during fabrication and assembly processes.
Typical 4140 forged steel products:
4140 steel is one of the most widely used carbon steel forgings for the machinery industries. They have excellent mechanical properties. We have abundant experience for the 4140 forgings. These 4140 forgings are ideal forging blanks for shafts, rods, rings etc.
4140 forged steel advantages:
4140 forged steel are alloy steel forgings containing high levels of chromium and molybdenum. 4140 alloy steel forgings have the characteristics of high strength, good hardenability, good toughness, and small deformation during quenching.
- High strength: The strength of 4140 steel forgings belongs to high-strength alloy steel forgings, with high yield strength and high tensile strength.
- Good hardenability: After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
- Good toughness: 4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
- Small deformation during quenching: 4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
- High high-temperature creep strength and endurance strength: 4140 steel forgings have good strength and endurance performance at high temperatures.
What is 4140 forged steel good for?
4140 forged steel is the ideal material for the manufacturing of various key parts, including large gears, crankshafts, heavy duty shafts, hydraulic cylinder rods, and oil and gas equipment. 4140 forged steel are your good choice when the parts require high strength and wear resistance.
