Home > Invar 42 Pipe
Rithav Pipes and Tubes, based in Delhi, India, stands out as a top manufacturer and supplier of Invar 42 Pipes, specifically designed for situations where minimal thermal expansion and outstanding dimensional stability are crucial. Invar 42 is a nickel-iron alloy with 42% nickel, celebrated for its low thermal expansion coefficient and impressive structural integrity. At Rithav, we provide meticulously crafted Invar 42 seamless and welded pipes that comply with international standards like ASTM F1684. These pipes find extensive use in industries such as electronics, aerospace, cryogenics, and telecommunications, where temperature fluctuations necessitate stability, reliability, and high-performance materials.
Invar 42 Pipes consist of about 58% iron and 42% nickel, along with small amounts of carbon, manganese, silicon, and chromium. This unique blend results in a very low thermal expansion coefficient (~4.8 × 10⁻⁶/°C between 20°C–300°C). The mechanical properties include a tensile strength ranging from 450 to 620 MPa, a yield strength of at least 275 MPa, and an elongation of 25 to 35%, depending on the heat treatment. Invar 42 is known for maintaining structural stability even with temperature fluctuations, offering good toughness, moderate corrosion resistance, and excellent weldability, making it perfect for high-precision components that experience thermal cycling.
