Hydrogen Induced Crack Resistant Steel Plates

HIC (Hydrogen Induced Cracking), which occurs under environments where water coexists with hydrogen sulfide (H2S), and SSCC (Sulfide Stress Corrosion Cracking), which occurs under a certain stress, are serious problems in tanks, pressure vessels, and linepipes.
JFE Steel supplies reliable steel plates with substantially improved resistance to HIC and SSCC by reducing impurity elements and controlling the morphology of inclusions.
