* Severstal to report Q3 financials on Oct 18

MOSCOW, Oct 17 (Reuters) - Severstal, Russia's fourth-largest steel producer, is expected to post third-quarter core earnings of $633 million on Wednesday, a Reuters poll of six analysts showed. The firm posted earnings before interest, taxation, depreciation and amortisation (EBITDA) of $584 million in the same period last year. Controlled by billionaire Alexei Mordashov, Severstal has said its third-quarter steel product sales rose by 8 percent year on year due to stronger domestic demand. The increased demand and the construction season also helped sales of its accumulated stocks of high value-added products.
