Aiman Metals stands out as a reliable manufacturer and supplier based in Kuala Lumpur, Malaysia, specializing in top-notch Alloy Steel AISI 4130 Bars and Rods designed for tough engineering and industrial tasks. These bars and rods are celebrated for their remarkable strength, toughness, and weldability, making them a go-to choice in structural and high-pressure settings. At Aiman Metals, we take pride in crafting these products with precise dimensions, smooth finishes, and a commitment to international quality standards. Our AISI 4130 Bars and Rods come in a variety of sizes, lengths, and heat-treated conditions, serving industries like oil and gas, aerospace, automotive, and heavy machinery.
Alloy Steel AISI 4130 Bars and Rods are low-alloy steels that typically contain around 0.28–0.33% carbon, 0.40–0.60% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum, along with trace amounts of silicon and sulfur. This unique blend offers an impressive balance of strength, ductility, and resistance to corrosion. Their mechanical properties usually feature a tensile strength ranging from 560–670 MPa, a yield strength of about 460 MPa, and solid fatigue resistance, which can be further improved through heat treatment methods like quenching and tempering.
