25CrMo Gear Steel Bar 101

Product Introduction Of 25CrMo Gear Steel Bar

25CrMo gear steel bar is a kind of high performance alloy steel, mainly used in the manufacture of various gear parts. It combines high strength, good toughness, and excellent wear resistance, making it an ideal choice for manufacturing heavy-duty, high-precision gears.

The main chemical composition of 25CrMo gear rebar includes carbon (C), chromium (Cr), molybdenum (Mo) and other alloying elements. These elements give steel its unique physical and chemical properties. Its moderate carbon content ensures that the steel has a certain hardness and strength. The addition of chromium and molybdenum improves the hardenability and corrosion resistance of steel, so that it can maintain stable performance in harsh working environment.
