Max Tube Fittings is a well-respected manufacturer and supplier of Stainless Steel 304H Instrumentation Tube Fittings based in Delhi, India. They offer high-quality, dependable solutions for critical fluid and gas control systems. SS 304H is the high-carbon version of SS 304, crafted specifically for improved strength, creep resistance, and durability at higher temperatures. These tube fittings are designed to provide leak-proof, secure, and efficient connections in instrumentation, hydraulic, and pneumatic systems. With outstanding corrosion resistance, excellent mechanical properties, and a long service life, Max Tube Fittings’ SS 304H Instrumentation Tube Fittings are trusted in a variety of industrial applications.
Stainless Steel 304H Instrumentation Tube Fittings are made up of chromium (18–20%), nickel (8–11%), and a higher carbon content (0.04–0.10%), which boosts tensile strength and performance at high temperatures. They have a minimum tensile strength of 515 MPa, yield strength of 205 MPa, and remarkable ductility. The increased carbon content enhances creep resistance, making them perfect for high-temperature applications. With an austenitic microstructure, these fittings provide exceptional toughness, weldability, and durability. SS 304H Instrumentation Tube Fittings blend corrosion resistance with strength, ensuring reliability in critical industrial operations.
