Abstract

Sanicro 25 stainless steel (X7NiCrWCuCoNbNB25-23-3-3-2) is a preferred material for structural elements of boilers with supercritical and ultracritical parameters. Welded joints are critical sites that are vulnerable to failure. Hand-welded and automatically uniform welds of Sanicro 25 are evaluated in material studies, and the structure and basic mechanical properties of welded joints are examined. The proposed welding technology for Sanicro 25 ensures proper microstructure, and has obtained quality class B certification.
