Rough Forged Carbon Steel 35# 45# 42CrMo,42CrMo4 Forging Wheel Blank OEM

Rough Forged Carbon Steel 35# / 45# Wheel Blank – OEM Manufacturer & Supplier

We supply rough forged wheel blanks made from premium 35# and 45# carbon steel, designed for high-performance applications in cranes, port equipment, railways, mining trucks, and heavy-duty industrial machinery. These forged blanks feature excellent strength, impact resistance, and weldability—ideal for further machining and heat treatment.

As an OEM forging supplier, we provide fully customized wheel blank solutions based on customer drawings and technical specifications. Our wheel forgings are produced under stringent quality control standards to ensure uniform grain flow, minimized internal defects, and dimensional consistency.

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.

What is a Wheel Blank?

A wheel blank is a semi-finished forged component that serves as the raw form of an industrial wheel before final machining and assembly. Typically produced through hot forging, wheel blanks are designed to provide a strong and reliable base structure for cranes, mining trucks, port handling equipment, railcars, and other heavy-duty machinery.

Key Characteristics

• High Structural Integrity: Forged wheel blanks have excellent grain flow and density, minimizing internal defects and enhancing load-bearing performance.

• Customizable Geometry: Available in various diameters, hub designs, and flange profiles, tailored to fit different axle or track systems.

• Excellent Wear & Impact Resistance: Ideal for rolling and rotating applications exposed to continuous friction, shock, or high dynamic loads.

• Material Versatility: Commonly made from carbon steel (e.g., 35#, 45#) or alloy steels for improved strength and service life.

Common Types of Wheel Blanks

• Solid Forged Wheel Blanks: Without bore, typically used in rough terrain vehicles or mining carts.

• Flanged Wheel Blanks: With integrated or machined flanges, suitable for railway or crane tracks.

• Hollow Hub Wheel Blanks: With pre-bored center holes for easier machining and axle installation.

• Double-Rim or Wide-Profile Wheel Blanks: Designed for high-load equipment such as gantry cranes or rolling mills.

Advantages

• Excellent performance in shock load and rotating torque conditions

• Enhanced wear resistance through carburized surface layer

• Strong core ductility prevents cracking or brittle failure

• Material allows tight dimensional tolerances for gear finishing

• Available in custom sizes, one-off prototypes, or batch production
