Max Tube Fittings stands out as a reliable manufacturer and supplier of Stainless Steel 347 Instrumentation Tube Fittings based in Delhi, India. We pride ourselves on delivering top-notch solutions that ensure leak-proof and dependable connections in critical piping systems. SS 347, a stabilized austenitic stainless steel enriched with niobium (columbium), boasts remarkable resistance to intergranular corrosion, impressive high-temperature strength, and enhanced durability. Our instrumentation tube fittings are crafted with precision, guaranteeing safe and efficient handling of fluids or gases in demanding industries. With exceptional mechanical properties and corrosion resistance, Max Tube Fittings provides SS 347 Instrumentation Tube Fittings that meet international quality standards for global use.
Stainless Steel 347 Instrumentation Tube Fittings are made up of chromium (17–19%), nickel (9–13%), niobium, and trace elements, which together offer outstanding oxidation and creep resistance. The addition of niobium stabilizes the material, preventing carbide precipitation during welding and ensuring long-lasting stability at high temperatures. These fittings showcase high tensile strength (minimum 515 MPa), yield strength (minimum 205 MPa), and good elongation, making them perfect for high-pressure and high-temperature applications. With excellent ductility, hardness, and fatigue resistance, SS 347 Instrumentation Tube Fittings guarantee reliable leak-proof connections, even under varying conditions, ensuring a long service life and safe operation.
