摘要：the invention relates to a method for the manufacture of steel tubes and flatproducts (sheet and strip, seamless tubes) or containers used to issuetransport andprocess hydrocarbon gas containing co2 and liquid water and possibly small amounts ofh2s, and resistance to stress corrosion cracking by stress while having good weldabilityand 0.2% yield of at least 450 n \\/ a mm. we used a steel containing ni and having thefollowing composition (% by weight).0.015% c, 0.15, 0.50%, max. 2% mn, max. 20% p, max0.003%, 12.0 13.8% 0.002 - 0.02% cr and 0.01 - 0.05% nb, is iron and impurities.in theinvention, it is proposed that the ni content is limited to a maximum of 0.25%, the mncontent is not less than 1.0%, the c content is limited to 0.035%, and the productcomprises, as a constituent of alloys, 0.01 to 1.2% mo.
