Premium-grade Alloy Steel AISI 4130 Bars/Rods for high-performance engineering and industrial applications are available from Rupal Metals, a reputable manufacturer and supplier with headquarters in Delhi, India. These bars are perfect for use in demanding environments because of their exceptional strength, toughness, and weldability. Rupal Metals guarantees accurate dimensions, consistent quality, and dependable performance through rigorous adherence to international standards during manufacturing. Products of Rupal Metals’ AISI 4130 alloy steel meet vital requirements in the construction, automotive, oil and gas, and aerospace sectors by providing customised solutions that successfully tolerate high temperatures, pressures, and stresses.
Carbon (0.28–0.33%), chromium (0.8–1.1%), molybdenum (0.15–0.25%), manganese (0.4–0.6%), and silicon (0.15–0.35%) make up the majority of Alloy Steel AISI 4130 Bars/Rods. This low-alloy steel is renowned for its good ductility, high fatigue strength, and exceptional hardenability. Tensile strength of 560–670 MPa, yield strength of about 460 MPa, and elongation of about 20% are typical mechanical characteristics. Heat treatment improves the toughness and impact resistance of AISI 4130, which makes it appropriate for pressure-bearing and structural applications under a range of high-stress operating circumstances.
