Abstract: Horizontal continuous casting is widely used to produce semi-finished and finished metallic products. Homogeneity in metallurgical characteristics and mechanical properties in such products is of importance. In the present work microstructure and mechanical properties of a horizontal continuous cast pipe have been studied. Microstructural features were investigated by an optical microscope equipped with image analyzer and SEM was used to characterize precipitates. Tensile behavior, impact strength and hardness variations were the mechanical properties which were studied. Results showed that microstructure and mechanical properties had diversities in different parts of the pipe and distinct differences were observed between upper and lower parts of the pipe. A meaningful correlation was found in microstructure and mechanical properties in different parts of the component.
