Abstract
The purpose of the present invention is to provide a high strength thick walled electric resistance welded steel pipe having both excellent low temperature toughness and HIC resistance and having a yield strength of at least 400 MPa. In the present invention a steel raw material including by mass% 0.025 0.084% C 0.10 0.30% Si and 0.70 1.80% Mn the content of P S Al N and O being adjusted further containing 0.001 0.065% Nb 0.001 0.065% V 0.001 0.033% Ti and 0.0001 0.0035% Ca and satisfying a Pcm of 0.20 or less is subjected to hot rolling at a draft of at least 20% in the non recrystallization temperature range after being heated to and held in a temperature range of 1200 1280°C. After hot rolling is completed the steel raw material is cooled to a cooling stop temperature of 630°C or below at a cooling rate of 7 49°C/s and is wound into a hot rolled strip at 400°C to less than 600°C. The hot rolled steel strip is roll formed and electric resistance welded to obtain an electric resistance welded steel pipe and a welded part of the electric resistance welded steel pipe is furthermore subjected to thermal processing in which the welded part is heated so that the entire wall thickness reaches a temperature range of 800°C 1150°C and is then cooled to 630°C or below at an average cooling rate of 7 49°C/s. A high strength thick walled electric resistance welded steel pipe is thereby obtained in which both the parent material and the electric resistance welded part have excellent toughness and HIC resistance.
