Abstract

Formålet er å tilveiebringe et lavlegert stål for oljebrønnrør med utmerket sulfidspenningssprekkingsmotstand, egnet for et foringsrør eller rør for oljebrønner eller gassbrønner. Middelet for oppnåelse av dette er et lavlegert stål for oljebrønnrør med utmerket sulfidspenningssprekkingsmotstand inneholdende i masse%, C: 0,2 til 0,35 %, Si: 0,05 til 0,5 %, Mn: 0,05 til 1,0 %, P: 0,025 % eller mindre, S: 0,01 % eller mindre, Al: 0,005 til 0,10 %, Cr: 0,1 til 1,0 %, Mo: 0,5 til 1,0 %, Ti: 0,002 til 0,05 %, V: 0,05 til 0,3 %, B: 0,0001 til 0,005 %, N: 0,01 % eller mindre, O (oksygen): 0,01 % eller mindre, Nb: 0 til 0,1 %, Ca: 0 til 0,01 %, Mg: 0 til 0,01 % og Zr: 0 til 0,1 %, hvori halvverdibredden H og en hydrogendiffusjonskoeffisient D (10-6 cm2/s) tilfredsstiller den følgende ligning (l): 30H + D < 19,5 ligning (1)
