The best material for manufacturing train wheels depends on the type of train and the environment in which it operates.

Rail passenger car wheels:

Suggested material: Carbon structural steel such as 60#, 65#.

Characteristics: Moderate strength and hardness, suitable for regular passenger trains.

Railway wagon wheels:

Suggested materials: spring steel, e.g. 65Mn, and alloy structural steel, e.g. 42CrMoA.

Characteristics: Higher strength and abrasion resistance, suitable for wagons with long time and high load transport.

High-speed railway wheels:

Recommended material: Alloy steel, such as ZG430-640.

Characteristics: Higher strength and hardness to meet the operating requirements of high-speed trains.

Light rail wheels:

Suggested material: Carbon structural steel, such as 60#, 65#, or suitable material according to the specific requirements of light rail system.

Characteristics: Balance of light weight and strength

Metro wheels:

Recommended material: Carbon structural steel, such as 60#, 65#, or special lightweight alloy.

Characteristics: Frequent stops at metro stations and intensive operations usually require the use of lightweight alloys.

Therefore, it is necessary to choose the appropriate material according to the usage scenario of the railway wheels.
