The mild steel with low phosphorus is vulnerable to corrosion while higher phosphorus often results in hot crack by fusion welding. The present study evaluated microstructures and mechanical properties of high phosphorus steels joined by friction stir welding below the A 1  temperature. The microstructure was analysed considering various phosphorus contents, and mechanical properties were assessed by digital image correlation. The results suggest that alloying elements (nickel, chromium and niobium) contribute to the refinement of pearlite in the base metal and cementite in the stir zone. The increasing phosphorus improves the microhardness and strength of friction stir welded joints but weakens the ductile behaviour. The added alloying elements can enhance the ductile behaviour and mechanical strength at the same time.
