A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes NbCr and/or NbCrNx in certain embodiments of this invention. The use of such materials as an IR reflecting layer(s) enables the coated article to have good corrosion resistance to alkaline solutions, good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ΔE* value(s)) upon heat treatment (HT). The coated article may be heat treated (e.g., thermally tempered) in certain example embodiments of the invention.
