With a keen emphasis on durability, corrosion resistance, and customer satisfaction, Ojas provides precision-engineered tubing solutions that adhere to international standards. Monel 400, a solid-solution alloy made of nickel and copper, boasts remarkable resistance to seawater, acids, and alkalis. Perfect for the marine, chemical, and oil & gas sectors, Ojas’s Monel 400 Tubing guarantees a long service life, even in challenging conditions, making it the go-to choice for critical industrial applications.
Monel 400 Tubing consists of about 63% nickel and 30–34% copper, along with trace amounts of iron (2.5%), manganese, carbon, and silicon. This unique blend gives it outstanding corrosion resistance, particularly in saltwater and acidic settings. The tubing showcases a tensile strength ranging from 550 to 620 MPa and a yield strength of approximately 170 to 345 MPa, all while maintaining excellent ductility and toughness across a broad temperature spectrum. It performs exceptionally well in both sub-zero and high-temperature conditions, ensuring good weldability and workability, making it a reliable choice for demanding and corrosive industrial environments.
