With a strong commitment to consistency, technical precision, and timely delivery, the company meets the rigorous demands of industrial needs with reliable alloy steel solutions.
Alloy Steel AISI 4130 is a low-alloy steel that contains about 0.28–0.33% carbon, 0.8–1.1% chromium, and 0.15–0.25% molybdenum. It boasts high tensile strength (typically ranging from 670 to 880 MPa) and good hardenability, which makes it perfect for heat treatment processes like quenching and tempering. AISI 4130 also offers excellent toughness, solid fatigue strength, and high impact resistance. Its good machinability and exceptional weldability—qualities that are hard to find in high-strength steels—make it particularly valuable in industries that demand both performance and fabrication flexibility.v
