Objective
In quantitative terms, 17 % Cr-AISI 430 ferritic stainless steels are second only to steels having the standard austenitic composition 18 Cr-10 Ni-AISI 304. The lengthy heat treatment is necessary in order to temper the martensitic structure of the hot strip and transform it into ferrite with a higher carbide content (M23C6), whilst at the same time ensuring homogenization of the composition of the ferrite-Cr carbides interface by Cr diffusion. Static annealing thus makes uncoiling of the hot strip possible and avoids intergranular corrosion in the subsequent pickling phase. The aim of these activities is the definition on a laboratory and pilot-plant scale of conditions suitable for the continuous annealing of 17 % Cr stainless ferritic steels. An industrial-scale feasibility study, which is compatible with existing plants, will also be carried out in respect of the solutions identified and the subsequent initial phase of industrialization will be initiated.
