Abstract

Den foreliggende oppfinnelse vedrører et høyfast sømløst stålrør som har utmerket bestandighet mot hydrogen-forårsaket sprekkdannelse, kjennetegnet ved at det består av, i masse%, C: 0,03 - 0,11 %, Si: 0,05 - 0,5%, Mn: 0,8 - 1,6%, P: 0,025% eller mindre, S: 0,003% eller mindre, Ti: 0,002 - 0,017%, Al: 0,001 - 0, 10%, Cr: 0,05 - 0,5%, Mo: 0,02 - 0,3%, V: 0,02 - 0,20%, Ca: 0,0005 - 0,005%, N: 0,008% eller mindre og O (oksygen): 0,004% eller mindre og resten Fe og urenheter, og også ved at mikrostrukturen i stålet er bainitt og/eller martensitt, ferritt er utfelt på korngrenser, og flytegrense er 483 MPa eller mer. Videre, for å sørge for høy fasthet av stålet, inneholder det sømløse stålrør fortrinnsvis, i masse%, i det minste det ene av Cu: 0,05 - 0,5% og Ni: 0,05 - 0,5%. For å produsere det ovennevnte stålrør er det ønskelig å begrense en utgangstemperatur for bråkjøling etter valsing, en avkjølingshastighet og en anløpingstemperatur. Ved hjelp av denne konfigurasjonen kan det tilveiebringes et sømløst stålrør som har en flytegrense på 483 MPa eller mer og utmerket HIC-bestandighet, hvilket er egnet for en rørledning.
