1.Ferritic corrosion-resistant steels are characterized by differing instability of the a-solid solution in cold reduction depending upon the silicon, manganese, and chromium contents. With a 15% Cr content in the steel to obtain a ferritic structure stable in reduction it is necessary to add up to 1.5% Si to it. An increase in manganese content to more than 1% leads to the appearance of unstable austenite.2.In cold reduction of the steel with 15% chromium with an increase in stability of the ferritic structure as the result of alloying with silicon and also with an increase in chromium content to 17% the plasticity increases but the degree of strengthening decreases.3.To provide a sufficient level of plasticity of cold reduced ferritic corrosion-resistant steels with 15–18% Cr it is desirable to limit the manganese content in them to 0.5%.4.In production of cold-rolled ferritic corrosion-resistant steel an increase in plasticity is possible as the result of decreasing the degree of reduction to 25%. |
