Corrosion-resistant forged steel blank

The utility model discloses a corrosion-resistant forged steel blank which comprises a blank base body, a flow guide protruding eave is arranged on the outer wall of the blank base body, a protective layer is wrapped outside the blank base body, and a plurality of flow dividing grooves are evenly distributed in the outer wall of the protective layer. According to the utility model, anti-corrosion oil can be injected into the outer wall of the blank base body through the oil injection hole, and the anti-corrosion oil spirally flows downwards outside under the action of the flow guide convex eave and is absorbed by the sponge strip in the flowing process, so that the anti-corrosion oil is adhered to the outer wall of the blank base body to isolate and protect the blank base body; the anti-corrosion oil overflows to the outside of the protective layer through the oil injection hole, flows into the diversion grooves under the action of gravity, and flows into other diversion grooves through the diversion grooves,
