Material selection

High quality custom rail shoulders are usually made of high-quality materials to ensure their high strength, corrosion and wear resistance.

Cast iron

such as QT400-15, QT450-10, QT500-7 and other models of cast iron, with good strength and toughness, suitable for a variety of harsh environments.

Carbon steel and alloy steel

These materials have high strength and hardness to meet the needs of heavy duty and high-speed trains.

Stainless steel

With excellent corrosion resistance, suitable for rail shoulders exposed to wet or corrosive environment for a long time.
