Abstract

The central segregation chemical and microstructural heterogeneity in low-carbon low-alloy pipe steel plates produced from continuously cast slabs occupies a small region of the plate and does not substantially affect the conventional mechanical properties and cold resistance. However, it causes a discontinuity detected by ultrasonic inspection, decreases mechanical properties in the Z direction, increases the tendency to cracking in the weld zone, and, which is especially important for the pipes for sour service, increases the sensitivity to HIC (Pemov and Nosochenko in Metallurgist 47(11):460–464, 2003; Matrosov et al. in Probl Ferrous Metall Mater Sci 1:98–104, 2014).
