Zusammenfassung:Corrosion resistant steels having improved weldability particularly sea-water resistant steels comprising 0.001 - 0.25 percent of carbon, 0.7 - 1.1 percent of silicon, 0.3 - 2.0 percent of manganese, 0.5 - 2.0 percent of chromium, 0.1 - 1.5 percent of molybdenum. 0.1 - 0.29 percent of copper, less than 0.04 percent of phosphorus, two or more elements selected from the group consisting of arsenic, tin, beryllium, bismuth, lead, germanium, antimony, selenium and tellurium in an amount of 0.02 - 0.20 percent each, the balance being iron and unavoidable impurities.
