SAE4340 bar 4340 alloy steel 4340 round bar machining parts
SAE4340 is an alloy steel also known as chromium molybdenum steel.
It is usually used to manufacture mechanical parts with high strength, high hardness and high corrosion resistance
This material has excellent hardenability and good thermal stability and can withstand high temperatures and pressures.
During the manufacturing process, 4340 alloy steel usually needs to go through multiple processes, including smelting, forging, heat treatment and mechanical processing. Its manufacturing process is complex, but the parts made have high hardness and corrosion resistance and can meet many demanding application scenarios.
Strength and Toughness: 4340 Bar offers excellent strength and toughness
Wear resistance: 4340 bar has good wear resistance
High temperature performance: 4340 bar maintains good strength and hardness at high temperatures, making it suitable for applications in high temperature environments
Ease of processing: 4340 bar has good processing performance and can be used for common processing techniques such as heat treatment, machining and welding.
4340 alloy steel round bar is widely used in the aerospace industry because of its ultra-high strength. It is known for its toughness after heat treatment while maintaining good fatigue strength. This is an excellent choice for highly stressed parts. It can be processed by all conventional methods. The material is available in both vacuum melted (VM) and air melted (AM) forms.
4340 rod/bar has excellent strength, toughness and wear resistance, it is widely used in various industries and applications.
