Ductile ferritic steels and their use for metallic articles, especially welded constructions |
摘要 |
Ferritic, stabilized, stainless and corrosion-resistant chromium-molybdenum steels with a carbon content of from 0.01 to 0.025%, a nitrogen content of from 0.005 to 0.025%, a chromium content of from 20.0 to 30.0%, a molybdenum content of from 3.0 to 5.0%, manganese and silicon contents of from 0.02 to 1.0% in each case and vanadium, tungsten, cobalt and aluminum contents of at most 0.25% in each case and also with a nickel content of from 3.2 to 4.8%, a copper content of from 0.1 to 1.0%, a titanium content of from 0.2 to 0.7% and/or a niobium content of from 0.2 to 1.0%, the rest being iron with the usual impurities, alloying additions of boron and/or zirconium being permitted in quantities which correspond to the prior art.
