Abstract
The invention relates to a high-silicon-content corrosion-resistant austenitic steel, characterized by alloying contents (in % by weight) of ______________________________________ max. 0.2% C 10 to 25% Ni 8 to 13% Cr 6.5 to 8% Si 0 to 10% Mn and/or Co max. 0.010% S max. 0.025% P ______________________________________ residue iron and the usual admixtures and impurities due to manufacture. The steel is suitable as a material for the production of corrosion-resistant articles for the handling of highly concentrated hot sulphuric acid, highly concentrated hot nitric acid and other strongly oxidizing media, such as chromic acid, in the form of rolled plates, strips, pipes, rods, wires and other forms of product.
