Test range

Track material hardness test mainly covers the following types of track materials:

Steel rails: including ordinary rails, heat-treated rails, alloy rails, etc.

Alloy materials: alloy materials used to manufacture track components, such as aluminum alloys, copper alloys, etc.

Other composite materials: composite track materials used in special occasions.

Test items

Track material strength test items mainly include the following aspects:

Tensile strength: The maximum tensile stress that a material can withstand before breaking is determined by tensile test.

Yield strength: The stress at which a material undergoes plastic deformation without breaking during stretching.

Hardness test: Although hardness is not an indicator that directly reflects strength, there is a certain correlation between hardness and strength, so hardness test is also often used to evaluate the mechanical properties of track materials.

Impact toughness: The ability of a material to resist deformation and fracture when subjected to impact loads.

Fatigue strength: The ability of a material to resist fatigue damage under repeated loading and unloading conditions.
