High Temperature Seamless Steel Tube

Product Description High-Temperature Oxidation Resistance: Forms a dense, adherent oxide film (such as Cr₂O₃ in stainless steel) to prevent material degradation. For example, 310S remains stable in continuous service at 1000°C with minimal weight loss (<0.1 g/m²·h). Creep and Rupture Strength: Resists permanent deformation under long-term high-temperature stress. 12Cr1MoVG exhibits a creep strength of 80 MPa for 100,000 hours at 540°C, meeting standards for power plant boiler tubes. Thermal Stability: Avoids phase transformation or grain coarsening. Nickel-based alloys (such as Haynes 282) maintain a uniform microstructure even after 10,000 hours of operation at 1050°C. Corrosion Resistance: Resists corrosive media (such as steam, flue gases, and chemical reagents). 347H is the material of choice for sour steam environments at 600–800°C due to its resistance to intergranular corrosion.
