Inox Steel India
Inox Steel India is a leading manufacturer, stockist, and global exporter of Seamless Boiler Tubes conforming to ASTM A210, ASTM A213, and DIN 17175 standards.
These tubes are engineered for high-temperature and high-pressure service in boilers, superheaters, reheaters, economizers, heat exchangers, and thermal power generation units.
Our boiler tubes operate reliably under the harshest operating conditions involving:
With precision manufacturing, strict heat-treatment control, advanced NDT testing, and full certification, Inox Steel India supplies boiler tubes for power plants, refineries, petrochemical units, sugar factories, industrial boilers, HRSG units, and process heating systems across India, GCC, Africa, Europe, USA, South Asia, and South America.
Boiler tubes must withstand extreme mechanical and thermal conditions. The materials and standards ensure:
Because of these critical needs, industries rely only on globally proven standards like ASTM A210, ASTM A213 & DIN 17175.
