Abstract

Foreliggende oppfinnelse vedrører stålrør med høy mekanisk motstand ved romtemperatur og opp til 130°C, god seighet og god korrosjonsbestandighet i metallbasen så vel som god motstand mot sprekkdannelse i de varmepåvirkede sonene (HAZ) straks røret er sveist sammen, og mer spesifikt til sømløse stålrør av store dimensjoner med høy mekanisk motstand, god seighet og god korrosjonsbestandighet, kalt bærelineledningsrør. Fordelene med foreliggende oppfinnelse med hensyn til kjente løsninger ligger i å frembringe en kjemisk komposisjon for stål som benyttes for å fremstille sømløse stålrør av store dimensjoner med høy mekanisk motstand, god seighet, og god spalting for fremstilling av dette produktet. Disse fordelene oppnås ved å benytte en komposisjon som hovedsakelig utgjøres av Fe og en spesifikk kjemisk komposisjon.
