Inox Steel India is a leading manufacturer, stockist, and global exporter of Stainless Steel Heat Exchanger Tubes made as per EN 10216-5 in the premium grade X2CrNi18-10 (Werkstoff 1.4307) — equivalent to SS 304L (UNS S30403). With high corrosion resistance, excellent formability, and enhanced weldability due to low carbon content, this grade is widely used in heat exchangers, condensers, refinery coolers, boilers, chemical evaporators, and thermal processing systems.
We supply tubes in a wide range of OD, wall thickness, and delivery conditions (Annealed, Cold Finished, Bright Annealed), with full EN 10204 3.1 / 3.2 certifications. Our tubes are engineered to perform reliably in steam service, mild corrosive media, heat transfer systems, and moderate chloride environments, making them ideal for oil & gas, power plants, petrochemical units, and industrial heat-exchange systems.
Our manufacturing facilities are equipped with advanced cold-drawn lines, bright annealing furnaces, U-bending systems, and automated NDT equipment, ensuring consistency, dimensional accuracy, and long service life of every heat exchanger tube supplied.
X2CrNi18-10 is the EN designation for low-carbon austenitic stainless steel 304L. It contains:
This composition significantly improves resistance to: Intergranular corrosion, Sensitization during welding, Chloride-containing water at low to medium temperature, and Steam and condensate service. The grade is preferred for heat exchanger tubes because it offers a reliable balance of corrosion resistance, mechanical stability, weldability, and cost efficiency. These properties make X2CrNi18-10 a global standard for low-temperature and moderate corrosive heat-transfer environments.
These tubes are engineered to withstand rigorous thermal cycles while maintaining structural integrity and high flow efficiency.
Inox Steel India follows a strict, multi-stage manufacturing process to achieve precision, reliability, and performance:
This ensures reliability in high-heat, high-flow, and steam-pressure applications.
