Abstract
Et lavlegert stål inneholdende, i vektprosent, C 0,03-0,13 %, Mn 0,90-1,80 %, Si = 0,40 %, P = 0,020 %, S = 0,005 %, Ni 0,10-1,00 %, Cr 0,20-1,20 %, Mo 0,15-0,80 %, Ca = 0,040 %, V 5 = 0,10 %, Nb = 0,040 %, Ti = 0,020 % og N = 0,011 % til fremstilling av høyfast, sveisbart, sømløst stålrør, kjennetegnet ved at stållegeringens mikrostruktur er en blanding av bainitt og martensitt og flytespenningen er i det minste 621 MPa (90 ksi). Det er et andre formål med den foreliggende oppfinnelse å tilveiebringe et høyfast, sveisbart, sømløst stålrør som omfatter en stållegering inneholdende, i vektprosent, C 0,03-0,13 %, Mn 0,90-1,80 %, Si = 0,40 %, P = 0,020 %, S = 0,005 %, Ni 0,10-1,00 %, Cr 0,20-1,20 %, Mo 0,15-0,80 %, Ca = 0,040 %, V = 0,10 %, Nb = 0,040 %, Ti = 0,020 % og N = 0,011 %, også kjennetegnet ved at stållegeringens mikrostruktur er overveiende martensitt og flytespenningen er i det minste 690MPa (100 ksi).
