The Effects of Rolling Process on Microstructures of High Nb X70 Grade Pipeline Steel

Abstract:

In Gleele-3500 thermal simulation test machine, conduct thermal simulation experiment for high niobium X70 grade pipeline steel at different heating temperature, deformation temperature, deformation extent, cooling rate and coiling temperature. Analysis that the microstructure was influenced by different heating temperature and rolling process. The results showed that, For high niobium X70 grade pipeline steel, controlled heating temperature was1200±20°C, using HTP process, in large cooling rate range all can get the uniform acicular ferrite microstructures.
