Abstract (en)
[origin: EP0570985A1] A corrosion-resistant Fe-Cr alloy for use in corrosive atmosphere near a seashore or in a chemical plant has a composition containing approximately not less than 5 wt% of Cr, not more than 100 ppm of C, N, O and S in total, from 0.01 to 1.0 wt% of P and the balance substantially Fe and impurities. The alloy may further contain not more than about 1.0 wt% of Al, not more than about 1.0 wt% of Si and not more than about 1.0 wt% of Mn, and at least one element selected from the group consisting of Ti, Nb, V, Zr, Ta, W and B in an amount which approximately meets the following condition (1). It is also possible to include at least one element selected from the group consisting of Ni, Co and Cu in an approximate amount which meets the following condition (2), and/or at least one element selected from the group consisting of Al, Si and Mn in an approximate amount which meets the following condition (3): 0.01 wt% </= Ti + Nb + Zr + V + Ta + W + 20B </= 1.0 wt% (1> 0.01 wt% </= Ni + Co + 2Cu </= 6 wt% (2> 1.0 wt% </= 3Al + 2Si + Mn </= 50 wt% (3) <IMAGE>
