X'inhu l-materjal A672 C65?
A672 GrC65 CL22 belongs to the carbon-manganese-silicon steel series. Its chemical composition is meticulously designed, with carbon content controlled below 0.22%, manganese content between 1.0-1.5%, and appropriate silicon added to enhance strength and toughness. This alloy formulation enables the steel pipe to maintain good plasticity while possessing high yield strength (>415MPa) u saħħa tat-tensjoni (Akbar minn jew ugwali għal 485MPa).
Partikolarment notevoli huwa li wara li jgħaddi minn proċessi ta 'rolling u tkessiħ ikkontrollati speċjali, il-materjal jikseb effetti sinifikanti ta' raffinar tal-qamħ u toughness eċċellenti ta 'impatt ta'-temperatura baxxa, li jissodisfa bis-sħiħ ir-rekwiżiti tas-servizz f'-46 grad. Rigward ir-reżistenza għall-korrużjoni, permezz taż-żieda ta 'elementi ta' mikro-liga u kontroll strett tal-kontenut ta 'kubrit u fosfru, ir-reżistenza tagħha għal HIC (Hydrogen Induced Cracking) u SSC (Sulfide Stress Corrosion Cracking) tissodisfa l-istandards NACE MR0175, li jagħmilha partikolarment adattata għal kundizzjonijiet operattivi ħarxa li fihom sulfide tal-idroġenu.
