A Comparison of As-Welded and Stress-Relieved 2¼Cr-1Mo Steel Electroslag Weldments: Microstructure and Properties

Source

Electroslag weldments of 102-mm (4-in.)-thick annealed 2¼Cr-1Mo steel have been microstructurally and mechanically evaluated in the following conditions: aswelded, stress relieved at 690°C, and stress relieved at 760°C. The fusion zones and heat-affected zones were significantly toughened by postweld heat treatment, a result attributed to changes in the carbide composition and morphology caused by tempering.
