Abstract
Oppfinnelsen beskriver stuket fleksibelt stålstigerør med ny kjemisk lav-karbon sammensetning og mikrostruktur, så vel som metode for framstilling av dette, hvilket medfører oppnåelse av høyere forbedring i levetid ettersom dette henger sammen med stigerørets segment i nedslagsfeltet. Lavkarbon stuket fleksibelt stålstigerør oppnår de ønskede egenskaper ved at det utsettes for varmebehandling. Den nye lavkarbon kjemiske sammensetning og mikrostruktur omfatter i vektprosent, karbon 0.04-0.10, mangan 0.40-0.70, silisium 0.15-0.35, krom 0.40-0.70, molybden 0.40-0.70, nikkel 0.10-0.40, nitrogen maksimum0.008, aluminium 0.010-0.045, svovel maksimum 0.005, fosfor maksimum 0.020, titan 0.003-0.020, niob 0.020-0.035, vanadium ikke mer enn 0.10, kobber maksimum 0.20, tinn maksimum 0.020, og maksimum 0.43 karbonekvivalent samt PCM ikke mer enn 0.23 og med en flytegrense på minst 65000 psi, bruddfasthet på minst 77000 psi og et forholdstall YS/UTS (flytegrense/bruddfasthet) mindre enn 0.89 i materiale representativt for rørlegeme, overgangssone og stuket endestykke.
