| Abstract: | Experimental rolling of X70 pipeline steels was conducted successfully in the 2300 production line of BX STEEL by composition design according to low C-Mn-Nb acicular ferrite steel and controlling of heating temperature,reduction,final-rolling temperature,cooling rate and coiling temperature during rolling process. The result showed that the microstructure of X70 pipeline steels was mainly acicular ferrite with good mechanical properties. |
