Abstract

Et tykkvegget sømløst stålrør for ledningsrør med høy fasthet og økt seighet, hvilket har en kjemisk sammensetning, i masse%, som består av C: 0,03 til 0,08%, Si: ikke mer enn 0,25%, Mn: 0,3 til 2,5%, Al: 0,001 til 0,10%, Cr: 0,02 til 1,0%, Ni: 0,02 til 1,0%, Mo: 0,02 til 1,2%, Ti: 0,004 til 0,010%, N: 0,002 til 0,008% og totalt 0,0002 til 0,005% av minst én valgt fra Ca, Mg og REM, og resten Fe og urenheter, valgfritt inkludert V: 0 til 0,08%, Nb: 0 til 0,05% eller Cu: 0 til 1,0%, og at P og S blant urenheter ikke er mer enn 0,05% henholdsvis ikke mer enn 0,005%. Det kan inneholde 0,0003 til 0,01% bor. En fremgangsmåte for fremstilling av dette er karakterisert ved avkjølingshastighet, oppvarmingsbetingelse for hulling og varmebehandling etter rørfremstilling.
