摘要
A fired heater tube that is resistant to corrosion and fouling is disclosed. The fired heater tube comprises an advantageous high performance coated material composition resistant to corrosion and fouling comprises: (PQR), wherein P is an oxide layer at the surface of (PQR), Q is a coating metal layer interposed between P and R, and R is a base metal layer, wherein P is substantially comprised of alumina, chromia, silica, mullite, spinels, and mixtures thereof, Q comprises Cr, and at least one element selected from the group consisting of Ni, Al, Si, Mn, Fe, Co, B, C, N, P, Ga, Ge, As, In, Sn, Sb, Pb, Sc, La, Y, Ce, Ti, Zr, Hf, V, Nb, Ta, Mo, W, Re, Ru, Rh, Ir, Pd, Pt, Cu, Ag, Au and mixtures thereof, and R is selected from the group consisting of low chromium steels, ferritic stainless steels, austenetic stainless steels, duplex stainless steels, Inconel alloys, Incoloy alloys, Fe-Ni based alloys, Ni-based alloys and Co-based alloys.
