Fiaz Pipes, based in Manama, Bahrain, stands out as a trusted manufacturer and supplier of AISI 4140 Tubing, providing top-notch alloy steel solutions tailored for tough industrial needs. Renowned for its durability, strength, and precision, AISI 4140 Tubing is the go-to choice for systems that face high pressure, dynamic loads, and extreme temperatures. Fiaz Pipes guarantees that every tube adheres to rigorous international standards, ensuring exceptional dimensional accuracy, consistency, and mechanical reliability. Their 4140 tubing is a favorite in the oil & gas, automotive, aerospace, and mechanical engineering sectors, delivering reliable performance even in the harshest environments where toughness and long-lasting durability are essential.
AISI 4140 Tubing is crafted from a chromium-molybdenum low-alloy steel that contains 0.38–0.43% carbon, 0.75–1.10% chromium, and 0.15–0.25% molybdenum, with added manganese and silicon to boost strength and ductility. This unique blend offers remarkable hardenability, wear resistance, and overall mechanical strength. Typical characteristics include impressive tensile strength (around 655–850 MPa), robust yield strength, excellent fatigue resistance, and solid impact toughness. AISI 4140 remains dependable under high stress, heat, and continuous mechanical loading, making it ideal for both normalized and quenched-and-tempered conditions.
