Abstract (en)
Structural steel of high resistance to intergranular stress corrosion cracking, especially in nitrate solutions, and of good weldability consists of (in per cent by mass): 0.01 to 0.04 % of carbon up to 0.012% of nitrogen 0.08 to 0.22% of titanium, with the proviso that Ti = 3.5 (C+N) 0.2 to 2.5% of manganese 2.0 to 5.5% of chromium 0.01 to 0.10% of aluminium up to 0.5% of silicon up to 1.0% of nickel up to 0.02% of phosphorus up to 0.02% of sulphur, the remainder being iron and unavoidable impurities. <IMAGE>
