Investigation into the influence of laser melting on the sulphide inclusions in AISI 416 stainless steel

► Laser surface treatment reduces sulphide inclusion size from over 2 μm to below 0.5 μm. ► Total volume of sulphur in stainless steel not reduced by laser surface treatment. ► Pitting potential in 500 ppm chloride increases by more than 200 mV. ► Inverse linear relationship between pitting potentia...
