Abstract
A heat transfer component that is resistant to both corrosion and fouling is disclosed having a heat exchange surface formed from a silicon containing steel composition including an alloy and a non-metallic film formed on a surface of the alloy. The alloy is formed from the composition η, θ, and τ, in which η is a metal selected from the group consisting of Fe, Ni, Co, and mixtures thereof, θ is Si, and τ is at least one alloying element selected from the group consisting of Cr, Al, Mn, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Sc, La, Y, Ce, Ru, Rh, Ir, Pd, Pt, Cu, Ag, Au, Ga, Ge, As, In, Sn, Sb, Pb, B, C, N, P, O, S and mixtures thereof. The non-metallic film comprises sulfide, oxide, carbide, nitride, oxysulfide, oxycarbide, oxynitride and mixtures thereof. The surface roughness of the heat transfer component is less than 40 micro inches.
