Abstract

THE AIM OF THIS STUDY WAS TO ANALYZE THE FAILURE OF A DRIVE SHAFT IN A HOT ROLLING MILL IN A STEEL INDUSTRY. THE SHAFT WAS FABRICATED FROM SF 60 STEEL GRADE AND WAS RECOVERED BY WELDING AND THEN MACHINED. FOR CHARACTERIZATION, CHEMICAL COMPOSITION ANALYSIS, METALLOGRAPHIC CHARACTERIZATION AND TENSILE TESTING WERE CARRIED OUT. THE RESULTS OF CHEMICAL COMPOSITION AND TENSILE TEST INDICATED THAT THE SHAFT MATERIAL COMPLIED WITH THE SPECIFICATIONS FOR GRADE SF 60. THE METALLOGRAPHIC ANALYSIS SHOWED THAT THE CRACK STARTED IN A DISCONTINUITY PRESENT IN THE REGION RECOVERED BY WELDING
