Inox Steel India supplies ASTM A210 / ASME SA210 Seamless Boiler Tubes in Grades A1 and C, engineered for high-pressure steam generation and elevated-temperature service.
Designed for use in industrial boilers, superheaters, economizers, heat recovery units (HRU), and high-pressure piping, these tubes deliver excellent mechanical strength, wall uniformity, and long-term reliability.
ASTM A210 Grade A1 is the widely used cost-effective carbon steel grade, offering good temperature resistance and durability in steam circuits.
Grade C provides higher tensile strength and improved pressure-handling capability, making it suitable for more demanding boiler environments.
All tubes are manufactured using a precision-controlled seamless process that ensures consistent wall thickness and smooth internal surfaces for efficient heat transfer.
These tubes undergo hot finishing, cold drawing, normalizing & stress relief operations, ensuring dimensional accuracy and stability under cyclic thermal stresses.
ASTM A210 / SA210 boiler tubes are manufactured for high-pressure steam, elevated temperature service, and continuous thermal cycling.
Their medium-carbon steel composition provides excellent mechanical strength, weldability, and resistance to scaling inside boilers.
