AISI/SAE 4130 Carbon Steel Bar

AISI/SAE 4130 round steel is characterized by its unique chemical composition, which includes approximately 0.28-0.33% carbon, 0.8-1.1% manganese, 0.15-0.25% molybdenum, and 0.4-0.6% chromium. This combination of elements not only enhances the steel's mechanical properties but also contributes to its ability to withstand high temperatures and pressures. The round shape of this steel makes it particularly suitable for manufacturing components such as shafts, axles, and tubing, where uniform strength and reliability are paramount.
One of the standout features of AISI/SAE 4130 round steel is its adaptability to various heat treatment processes. Whether it’s normalized, quenched, or tempered, this alloy can be tailored to meet specific performance requirements, ensuring that it meets the rigorous standards of any project. Additionally, its excellent machinability allows for easy fabrication, making it a preferred choice for engineers and manufacturers alike.
