If you are looking for high-temperature stainless steel tubes with stable mechanical properties and reliable corrosion resistance, we offer 1.4948 stainless steel seamless pickled tubes specifically designed for demanding thermal and pressure applications. These tubes are widely used in boilers, superheaters, heat exchangers, petrochemical plants, power generation equipment, and high-temperature pressure piping systems.

EN 1.4948 stainless steel hot-rolled tubes (X6CrNiMoTi17-12-2) are a titanium-stabilized austenitic stainless steel containing approximately 16-18% chromium, 10-13% nickel, molybdenum, and titanium, exhibiting excellent resistance to intergranular corrosion, oxidation, and creep at high temperatures.

Our 1.4948 seamless pickled tubes are manufactured using hot extrusion or piercing, cold working, solution annealing, and pickling processes to remove scale formed during hot working, resulting in a clean surface that improves corrosion resistance and inspection reliability. They offer good tensile strength and creep resistance at temperatures up to 550-600°C, suitable for long-term high-temperature service. We offer various product forms, including 1.4948 seamless round tubes, SS 1.4948 thick-walled tubes, and custom lengths, with optional heat treatments and surface finishes available to meet specific project requirements.
