Effect of Alloying Elements on Notch Toughness of Basic Weld Metals (Report 6)

Effect of Sulphur and Phosphorus at the Presence of Manganese in the Silicon Deoxidation

Abstract

Manganese gives beneficial effect to the weld metal in the presence of sulphur and phosphorus. Transition temperature based on the 15 ft-lbs energy definition was lowered by the addition of manganese at the same contents of sulphur up to 0.06%, and manganese also raised the critical phosphorus contents from which transition temperature showed marked increase.
