18CrNiMo7 alloy steel bar is a nickel-chromium-molybdenum case hardening steel designed for components that require a hard wear-resistant surface and a tough core after carburizing and heat treatment. It is commonly supplied as round bar, forged bar or machined bar for heavy-duty gears, shafts, pinions and transmission parts. With good hardenability and impact resistance, 18CrNiMo7 steel is suitable for demanding mechanical engineering applications where load capacity and fatigue resistance are important.
Materials can be cut to required sizes according to customer specifications or project needs.
Different surface finishes can be supplied according to product type and application requirements.
Processing services such as cutting, machining, heat treatment or surface finishing can be arranged upon request.
Products are packed for international transportation with flexible delivery support for global buyers.
For high-strength, highly wear-resistant, and impact-resistant power transmission components.
Suitable for heavy-duty gears, gear shafts, gearbox components, wind power drive systems, mining machinery drive parts, core drive components for construction machinery, and more. This steel is ideal for parts requiring high surface hardness and high core toughness.| Item | Typical Information |
