| Abstract Scope |
Carbide morphology and distribution critically influence the sulfide stress cracking (SSC) susceptibility of quenched and tempered P110 steel. This study investigates the effect of tempering temperature and time on API 5CT-compliant P110 steel with two chromium variants.
Comprehensive microstructural characterization for varying tempering schedules, including double quench and tempering, is performed using optical microscopy and scanning electron microscopy (SEM). Carbide morphology is quantitatively analyzed and is used to understand SSC response based on NACE TM0177 Method A SSC testing. This is complemented by thermodynamic simulations using Thermo-Calc which predict equilibrium carbide phases and evaluate the influence of chromium content on carbide formation.
The study aims to establish a robust correlation between tempering parameters, carbide morphology and distribution, and sulfide stress cracking (SSC) susceptibility. This integrated approach seeks to define an optimal thermal processing window to develop a resilient microstructural framework tailored for mild sour service environments. |
