Abstract
Den fremlagte oppfinnelse angår et stål med høy strekk- styrke som omfatter, ved vekt: C: 0,03 til 0,20%, Si: 0,6 til 2,0%, Mn: 0,6 til 2,0%, Al: 0,01 til 0,08%, B: ikke mer enn 0,0020%, og N: 0,002 til 0,008% og valgfritt i det minste ett element valgt fra Cu, Mo, Ni, Cr, Nb, V, Ti, Ca, og REM, med balansen som består av Fe og uunngåelige urenheter, og en fremgangsmåte for å fremstille et stål med høy strekkstyrke, som vanligvis omfatter trinnene av: en blokk som omfatter de ovenfor nevnte kjemiske sammensetninger utsettes for varm- valsing eller alternativt varmvalsing etterfulgt av kontrol- lert valsing. Den fremlagte oppfinnelse muliggjør at utmat- ningssprekking av det allerede sveisede stålet, i sin varme- påvirkede sone, forhindres, og samtidig forhindres eller hemmes spredningen av sprekkdannelse.
