09CrCuSb (ND Steel) Seamless Steel Tube
The 09CrCuSb (ND Steel) seamless steel tube is a specialized material that relies heavily on the presence of chromium (Cr), copper (Cu), and antimony (Sb) to provide its exceptional corrosion-resistant properties. The chromium content enhances the tube’s resistance to oxidation and corrosion, while the copper addition improves its resistance to sulfuric acid and other acidic environments. The presence of antimony further enhances the tube’s mechanical properties, making it more durable and resistant to wear and tear. The balanced composition of these key elements allows the 09CrCuSb (ND Steel) seamless steel tube to withstand the harsh conditions found in industries such as oil, chemical, electric power, and metallurgical applications, making it an ideal choice for use in economizers, heat exchangers, air preheaters, waste heat boilers, chimneys, and other equipment.

Applications of 09CrCuSb (ND Steel) Seamless Steel Tube
Fossil Fuel Power Plants: Heat exchangers in power plants that burn coal or heavy fuel oil, where the flue gas contains sulfur oxides.
Industrial Processes: Heat exchangers used in various industrial processes that generate sulfur-laden gases, such as chemical plants or refineries.
Economizers: Pre-heat boiler feedwater using exhaust gases before entering the boiler itself.
Air Preheaters: Recover heat from exhaust gases to pre-heat combustion air, improving boiler efficiency.
Other Auxiliary Equipment: ND steel tubes can be used in various auxiliary equipment components that handle high-sulfur gas streams, such as ducts or scrubber systems.
