Maria Pipes and Tubes stands out as a top-notch manufacturer and supplier of high-quality AISI 4140 Pipes right in the heart of Kuala Lumpur, Malaysia. These alloy steel pipes are celebrated for their impressive strength, toughness, and wear resistance, making them perfect for tough industrial tasks. Crafted to meet international quality standards, AISI 4140 Pipes come in a variety of sizes, wall thicknesses, and specifications to cater to the unique needs of customers. Whether it’s the oil & gas, automotive, aerospace, or heavy machinery sectors, Maria Pipes and Tubes guarantees that each product is built for durability, precision, and a long lifespan, even in the most challenging environments.
AISI 4140 Pipes are made up of chromium (0.80–1.10%), molybdenum (0.15–0.25%), carbon (0.38–0.43%), manganese (0.75–1.00%), and silicon (0.15–0.35%), along with trace amounts of phosphorus and sulfur. This specific blend gives them a high tensile strength ranging from 655 to 895 MPa and a yield strength between 415 and 655 MPa, along with solid fatigue and impact resistance. The combination of chromium and molybdenum boosts their hardenability, corrosion resistance, and heat resistance, making AISI 4140 Pipes ideal for situations that involve mechanical stress and high temperatures.
