Chemical Composition of 1Cr25Ni20Si2 – High-Temperature Austenitic Stainless Steel • Carbon (C): ≤ 0.20% • Manganese (Mn): ≤ 1.50% • Phosphorus (P): ≤ 0.035% • Sulfur (S): ≤ 0.030% • Silicon (Si): 1.00 – 2.50% • Chromium (Cr): 24.0 – 26.0% • Nickel (Ni): 19.0 – 22.0% • Iron (Fe): Balance Applications: Best suited for high-temperature, oxidizing, and carburizing environments such as petrochemical reformers, thermal reactors, and industrial boilers. Uses • Protection of U-bend tubes in superheaters and reheaters in thermal and captive power plants • Shielding tube bends in waste heat recovery boilers (WHRBs) and HRSGs subjected to slag and heat erosion • Guarding return bends in petrochemical steam reformers and cracking furnaces • Coverage for curved tubes in chemical reactors exposed to oxidizing and acidic gases • Ideal for industrial plants where prolonged exposure to thermal cycling and aggressive gas media is common Features • High-temperature strength – Maintains mechanical integrity and structural stability in service temperatures exceeding 1000°C. • Superior oxidation resistance – High chromium and silicon content offers excellent protection against scaling in air and oxidizing environments. • Carburization resistance – Resists carbon infiltration in environments rich in hydrocarbons and flue gases. • Full U-bend shielding – Available in both inner and outer U-type configurations for complete coverage of critical curved tube areas. • Custom fabrication – Precisely manufactured to match tube radius, bend angle, and diameter for a secure, vibration-resistant fit. • Easy to install – Mountable using clamps, bands, or tack welds without the need for system disassembly or extended shutdown. Applications • thermal power stations – Used on U-bend tubes in high-temperature sections of superheaters and reheaters to prevent scaling and heat-related fatigue. Increases equipment life and operational efficiency. • petrochemical refineries – Installed in steam reformers, cracking furnaces, and heaters exposed to oxidizing and carburizing gases. Delivers consistent protection under continuous heat stress. • waste heat recovery units – Shields return bends in WHRBs and HRSGs from slag abrasion and flue gas corrosion. Enhances resistance to thermal cycling. • chemical and metallurgical plants – Ideal for reactors, synthesis gas units, and process heat exchangers operating under severe thermal and chemical loads. • cement and glass industries – Applied in high-temperature gas flow lines and heater tubes where scale resistance and mechanical protection are essential.
