Ojas Pipes and Tubes has made a name for itself as a leading manufacturer and supplier of AISI 4140 pipes in Kolkata, India. We specialize in providing high-performance alloy steel piping solutions that are perfect for demanding engineering applications. Our AISI 4140 pipes are celebrated for their strength, toughness, and wear resistance, all thanks to our use of advanced manufacturing techniques and strict quality standards. We serve a diverse array of industries, including automotive, oil and gas, mechanical engineering, and heavy equipment. At Ojas Pipes and Tubes, we are dedicated to delivering reliable, durable, and precisely crafted AISI 4140 pipes tailored to meet the specific needs of our customers, both locally and internationally.
AISI 4140 pipes are crafted from a chromium-molybdenum low alloy steel that contains about 0.38–0.43% carbon, 0.75–1.00% manganese, 0.80–1.10% chromium, and 0.15–0.25% molybdenum. These elements work together to provide exceptional hardenability, high fatigue strength, and impressive wear resistance. The mechanical properties of these pipes include a tensile strength ranging from 655 to 850 MPa, yield strength between 415 and 655 MPa, and an elongation of around 20%. They can also be heat-treated to enhance their mechanical performance, and their good machinability and impact resistance make them perfect for heavy-duty applications.
