Summary:An attempt has been made to study the continuous drive friction welding characteristics of AISI 430 ferritic stainless steel. All the welds exhibited fine equiaxed ferritic grains. Parameters that result in marginally coarse grain size in the bond zone led to low hardness and high toughness. Welds having a fine grain size exhibited higher hardness and superior notch tensile strength. An inverse relationship was observed between impact toughness and notch tensile strength. Regression analysis of the data revealed a high degree of correlation. It was concluded that the selection of parameters would depend on the property of interest.
