Products Description
The weight of 22 kg rail steel is clearly marked as about 22 kg per meter. This type of rail steel usually adopts the dimensions specified by national standards and has a specific cross-sectional shape. Generally speaking, its height, bottom width and waist thickness have strict standards to ensure the strength and stability of the rail steel to meet the high requirements of railway operation.
1. Yield strength:
This is an important parameter to measure the ability of rail steel to resist plastic deformation. The yield strength of 22 kg rails is usually higher, which can ensure that they can maintain the stability of their shape under high loads.
2. Tensile strength:
Rails need to withstand the weight and friction of trains, so tensile strength is the key to measure their quality. 22 kg rails were designed with this in mind, and their tensile strength can meet the harsh conditions of use.
3. Elongation:
The elongation performance of rails is also an important indicator when stretched by external forces. It reflects the plastic deformation ability of steel and plays an important role in preventing fractures.

FAQ
1.What certifications and standards do rail exports need to meet?
Different countries and regions have different certification and standard requirements for rail exports. Generally, it is necessary to meet the national standards of the target market, such as AREMA standards for exports to the United States and EN standards for exports to Europe. In addition, it may be necessary to pass relevant quality system certifications, such as ISO 9001 quality management system certification.
2.How to prevent rails from deformation during storage?
When storing rails, choose a flat and solid site and use appropriate support methods. For long rails, a support point should be set at a certain distance, and the support points should be kept on the same horizontal plane to prevent the rails from bending and deforming due to their own weight.
3.What is the impact of the surface quality of the rail on its performance?
Good surface quality can reduce friction during train operation, reduce noise, and improve the stability of train operation. Surface defects (such as cracks, scars, folds, etc.) can avoid damage to the rails due to stress concentration during use and extend the service life of the rails.
