Abstract

In this study, Hydrogen Induced Cracking (HIC) testing of high strength API 5L grade X70 linepipe hot rolled steel containing Ti was performed to investigate the effects of (Nb, Ti, V)(C, N) particles on HIC susceptibility. By controlling chemical composition and hot rolling parameters, experimental steel with Bainitic ferrite and Bainite microstructures was fabricated. HIC testing was carried out within an acidic condition (pH=2.7±0.1) according to NACE standards with test results showing cracking propagated along coarse (Nb, Ti, V)(C, N) particles at mid-thickness. This is mainly due to centerline segregation and hydrogen blistering between matrix and coarse (Nb, Ti, V)(C, N) particles without external stress.
