Abstract
Stress relieving is a common practice among manufacturing codes for reducing the magnitude ofresidual stresses in welded, quenched, and tempered steel structures and pressure vessels. The presentwork investigates the effect of stress relieving at 480, 560, 620, and 680°C on the microstructure andmechanical properties of 20 mm ASTM A517 Gr. B steel plate weldments produced by shielded metal arcwelding (SMAW). For this purpose, metallographic analysis, hardness measurement, charpy V notchedimpact test, and tensile test were performed. Result showed that stress relieving reduced the impacttoughness of all the base metals but better mechanical properties (hardness, tensile stress and impacttoughness) were achieved when it was accomplished at 560°C.
