What is the strength of road rail wheels with coating?

What is the strength of road rail wheels with coating?

2025-06-16

Strength of forged road or rail wheels —typically used in railway applications—can be characterized by several key mechanical properties. These wheels are usually made from high-strength steel and are manufactured through forging to ensure durability and performance under heavy loads.

The strength of forged road-rail wheels with coating remains fundamentally governed by the base material properties, but coating can enhance surface characteristics like wear resistance, corrosion resistance, and sometimes fatigue life. Here's a breakdown:

Effect of Coatings

Coatings do not increase the tensile or yield strength of the base wheel material, but they improve surface performance:

Summary for Coated Forged Road-Rail Wheels

Aspect Typical Value
Base Material Strength 850–1150 MPa (tensile), 450–900 MPa (yield)
Hardness (base) 250–320 HBW
Coating Thickness 50–300 microns
Coating Effect Improved wear, fatigue life, corrosion
Strength Gain (direct) None (mechanically), only indirect benefits
