| Abstract: | The Steckel rolling technology was simulated to produce X65 pipeline steel with acicular ferrite in laboratory. The microstructure and mechanical properties of simulation rolled X65 pipeline steel were studied with optical and electron microscopy and mechanical analysis. The results show that the X65 pipeline steel with acicular ferrite produced by Steckel mill rolling has excellent mechanical properties. The critical points are the formation of acicular ferrite by phase transformation strengthening and controlled rolling and cooling, and the reasonable size, shape and distribution of inclusions and carbon-nitride precipitates as well. |
