Beschreibung
Zusammenfassung:	metallurgy. SUBSTANCE: invention relates to high-strength corrosion- resistant steel that can be used in aviation, cosmic and other fields of industry for making power soldered-welded units used without thermal treatment after welding. Proposed corrosion-resistant steel has components in the following ratio, wt.-%: carbon, 0.03-0.08; chrome, 12.8-14.5; nickel, 5.2-6.5; molybdenum, 0.7-1.2; tungsten, 0.7-1.2; vanadium, 0.15-0.3; niobium, 0.08-0.3; nitrogen, 0.01-0.03; yttrium, 0.01-0.1; calcium, 0.001-0.01; zirconium 0.01-0.2; lanthanum, 0.01-0,1; iron, the balance. EFFECT: enhanced impact tenacity in soldered-welded articles working under cryogenic temperatures below -70 C. 3 tbl
