Function and Applications
Forged Railway Wagon Wheels are critical for supporting and guiding railway wagons along tracks, providing load-bearing capacity and stability under dynamic and static stresses. Their robust design ensures reliable performance in demanding rail environments, minimizing maintenance and enhancing safety. Commonly used in:

· Cargo Trains: Supporting freight wagons for heavy commodities like coal, ore, grain, or containers, with load capacities up to 50 tons per wheel.

· Mining Operations: Enabling rail-based transport of minerals and equipment in surface or underground mines.

· Industrial Rail Systems: Powering wagons in steel mills, cement plants, and sugar plants for bulk material transport.

· Port Logistics: Facilitating rail-mounted wagons for container and cargo handling in port facilities.

· Heavy Industry: Used in specialized rail systems for transporting oversized or heavy loads.

WALKSON’s railway wagon wheels are engineered to handle high axial loads, resist wear, and perform in extreme weather, ensuring operational efficiency. Contact us at info@walkson.com (mailto:info@walkson.com) to discuss your rail transport needs.

· AISI 1045 (ASTM A29): Equivalent to C45E, providing excellent toughness for railway wheels.

· AISI 4140 (ASTM A29): Equivalent to 42CrMo4, ideal for high-stress freight applications.

· AISI 4340 (ASTM A29): A high-strength alloy for extreme conditions in mining or heavy freight.

Materials are selected based on load, environmental exposure, and fatigue requirements. WALKSON provides material certification per EN 10204 3.1 or 3.2 standards, ensuring traceability and compliance.

Modern and Standardized Manufacturing Process

WALKSON employs a state-of-the-art manufacturing process for Forged Railway Wagon Wheels, adhering to international standards at every stage:

· Material Sourcing: High-quality steel ingots are procured from certified suppliers, verified for chemical composition and purity.

· Forging: Hot forging at 1,100–1,250°C using hydraulic presses (up to 10,000 tons) to create a dense, uniform grain structure for superior strength and fatigue resistance.

· Standard: ISO 6892-1 (tensile testing), ASTM E8/E8M.

· Heat Treatment: Normalizing, quenching, and tempering to achieve optimal hardness (HB 229–269 for 42CrMo4) and toughness.

· Standard: EN 10083-3, ASTM A29.

· Machining: CNC lathes and milling machines ensure precise wheel profiles, bore dimensions, and surface finishes (Ra 3.2 or better).

· Standard: ISO 2768 (tolerances), ASME Y14.5 (GD&T).

· Surface Treatment: Optional induction hardening (HRC 50–55) or anti-corrosion coatings (e.g., zinc-rich primer) for enhanced durability in harsh environments.

· Standard: ISO 12944 (corrosion protection).

· Inspection: Comprehensive quality checks using advanced equipment (detailed below).

Our ISO 9001:2015-certified facilities ensure consistent quality and traceability. We comply with EN 13262 (railway wheels) and AAR M-107/M-208 (Association of American Railroads standards) for railway applications.
