Effect of short-time overheating in the morphology of primary carbides network in Nb and NbTi-modified HP stainless steels steam reforming tubes

Effect of short-time overheating in the morphology of primary carbides network in Nb and NbTi-modified HP stainless steels steam reforming tubes

Commercial bulk hydrogen is mainly produced in petrochemical steam reforming furnaces inside centrifugally cast Nb-modified HP austenitic stainless steels tubes, which operate at temperatures above 900 °C. In-service aging causes well known microstructural modifications such as the transformation of...
