| Abstract Scope |
Medium carbon steels have excellent combination of tensile strength and ductility, low yield to tensile ratio, are cost effective and can be heat treated to different tube/pipe strength level based on their applications. Ultrasonic failure (cracks) causes the most rejections for pipe and tube makers. This contribution investigated the medium carbon tube and/or pipe cracking after forming and welding. Macro and microstructure study, and SEM EDX characterization indicated these cracks are caused by casting defects: inclusions in the slab from steelmaking, center line segregation, and slab internal cracking due to the improper casting parameter setups. |
