This material is equivalent to AISI 321 and is known for its excellent resistance to intergranular corrosion, especially after welding or prolonged high-temperature exposure. The addition of titanium in the alloy stabilizes the microstructure and prevents chromium carbide precipitation, making it ideal for thermal systems operating between 400°C and 900°C. The shield’s half-round design allows for quick and secure installation over existing tubes, providing durable protection in aggressive industrial environments. Chemical Composition of 1Cr18Ni9Ti – Titanium-Stabilized Austenitic Stainless Steel • Carbon (C): ≤ 0.08% • Manganese (Mn): ≤ 2.00% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): ≤ 1.00% • Chromium (Cr): 17.0 – 19.0% • Nickel (Ni): 8.0 – 11.0% • Titanium (Ti): ≥ 5 × C content • Iron (Fe): Balance Uses • Boiler Tube Protection – Guards tubes from high-temperature scaling and corrosion in superheater and reheater sections exposed to combustion gases. • Heat Exchanger Tubing – Reduces risk of thermal fatigue and corrosion in steam or process exchangers operating in elevated temperature zones. • Furnace Tube Shielding – Ideal for protecting radiant and convection zone tubes from oxidation and mechanical wear in refinery and chemical furnaces. • Petrochemical Piping – Prevents tube degradation in reformers, heaters, and gas coolers exposed to carburizing and oxidizing atmospheres. • Power Plant Steam Systems – Shields tubing in HRSGs and utility boilers operating under high-temperature and fluctuating load conditions. Features • Excellent Intergranular Corrosion Resistance – Titanium addition prevents carbide precipitation, making the shield ideal for welded and heat-cycled environments. • High-Temperature Stability – Performs effectively up to 850°C with consistent mechanical strength and oxidation resistance. • Austenitic Structure – Offers good ductility, toughness, and resistance to thermal shock and creep deformation. • Half-Round Precision Fit – Custom-formed to match tube diameters, ensuring tight coverage and easy field installation with clamps or welds. • Corrosion Protection – Withstands acidic flue gases, steam condensates, and other corrosive industrial byproducts. • Finishing Options – Supplied in bright annealed, pickled, or passivated finishes to suit operational and aesthetic needs. • Custom Dimensions – Available in various wall thicknesses, lengths, and diameters to suit different system designs and operating conditions. Applications • Thermal and Nuclear Power Plants – Protects boiler and superheater tubes from high-temperature stress and oxidation in base-load and cyclic operations. • Oil Refineries – Applied in fired heaters and reformers where tube protection from scale and corrosion is essential for system longevity. • Chemical Process Plants – Guards steam and fluid tubes in reactors and exchangers handling acidic or oxidizing media at high heat. • Fertilizer Industry – Shields ammonia converter and steam reforming tubes subjected to repeated thermal cycling. • Waste-to-Energy and Biomass Plants – Prevents erosion and degradation of tubes in flue gas zones with corrosive combustion byproducts. • Heat Recovery Steam Generators – Used in combined-cycle plants to extend the life of high-temperature steam tubing systems.
