Abstract

Stainless steel AISI 310 is one of the most widely used grades of heat-resistant stainless steel supplied into numerous industry sectors. The key properties of this material are its high chromium and medium nickel content making its resistance to oxidation, sulfidation and other forms of hot corrosion its main characteristics. This study investigates the influence of rotation speed and forging time during machining on responses of tensile strength and hardness. The turning was performed at various cutting speeds (550, 1020, and 1800 rpm) and forging time (25, 35, and 45 seconds). Response surface methodology was adopted in designing the experiments to quantify the effect of rotation speed and forging time on the friction welding responses. It was found that rotation speed was proportional to the tensile strength and was inversely proportional to hardness. Forging time was proportional to the tensile strength and was inversely proportional to hardness. Empirical equations developed from the results for all friction welding responses were shown to be useful in determining the optimum welding parameters range.
