Aman Pipes and Tubes, based in Hyderabad, India, has made a name for itself as a leading manufacturer and supplier of AISI 4140 Pipes. These pipes are crafted to provide robust and high-strength solutions for critical industrial needs. Made from a chromium-molybdenum alloy steel, AISI 4140 pipes are celebrated for their outstanding toughness, fatigue resistance, and wear performance. At Aman Pipes and Tubes, we produce seamless and precision-engineered AISI 4140 pipes that meet international standards, ensuring top-notch quality and precise dimensions. These pipes find their place in various industries, including oil & gas, mechanical engineering, automotive, and power generation. With a commitment to timely delivery and rigorous quality control, we cater to both local and global markets.
AISI 4140 is a low-alloy steel that contains about 0.38–0.43% carbon, 0.8–1.1% chromium, 0.15–0.25% molybdenum, and 0.75–1.0% manganese. This unique blend gives AISI 4140 pipes their impressive strength, toughness, and hardenability. Typically, these pipes boast a tensile strength between 655–850 MPa and a yield strength of around 415 MPa, which can vary based on heat treatment. They are recognized for their high fatigue strength, good impact resistance, and wear resistance. With the right techniques, these pipes are also easy to machine and weld, making them ideal for demanding environments where mechanical performance is crucial.
