Özet:

 


Steel
grades having high toughness and high strength are required for line pipes
since gas and oil should be transported through them at high pressures. Thermo-mechanically
controlled rolling processes are used for increasing both toughness and strength
at low temperatures since the line pipes are exposed to harsh climatic
conditions at full length and rather severe service conditions. Various test
methods such as Charpy, DWTT, CTOA have been used for measurement of toughness
values of these steels and the results have been evaluated considering various
criteria. In this study, thermo-mechanical rolling trials were performed at the
temperature below the recrystallization temperature of austenite on an API X70M
PSL2 grade steel, which is large scale used in the oil and natural gas line
pipes, to increase the strength without sacrificing the toughness. Different
reduction ratios were utilized and the effect of reduction ratios on mechanical
properties and microstructures were investigated during the trials. It was
observed that final grain size decreased and strength and toughness increased
with increasing reduction ratio.
