43kg Heavy Steel Rail Chinese Standard

The tensile strength of 43kg steel rails is generally high, reaching more than 850MPa. It has strong tensile strength and can withstand large external forces.

Yield strength refers to the maximum stress that a rail can withstand before permanent deformation occurs. The yield strength of 43kg rails can usually reach about 700MPa.

43kg steel rails have high hardness. After heat treatment, the surface of the rails has excellent wear resistance and can effectively resist long-term and repeated wear.

Although the 43kg rail has a high hardness, it still maintains a certain toughness. It will not brittle fracture under high load and high impact environment, and can ensure stable operation for a long time.

Advantages of 43kg heavy rails

Strong bearing capacity:

Due to its large mass, 43kg rails can share the huge pressure applied by trains, reduce the deformation and damage of the rails, and are especially suitable for heavy loads and high-frequency transportation.

Durability and wear resistance:

43kg rails are made of high-strength steel and undergo fine heat treatment, which has strong wear resistance and corrosion resistance, suitable for long-term use, and reduces the frequency of maintenance and replacement.

Good stability:

The large mass and solid structure make the 43kg rails extremely stable during train operation, which can reduce the vibration and

deformation of the rails and ensure the long-term stable operation of the railway system.

Strong adaptability:

43kg rails are suitable for a variety of railway systems, including high-speed railways, freight railways, urban rail transit and dedicated railways, and can provide effective rail support according to different usage scenarios.

Heavy Steel Rail

1. What is the minimum order quantity (MOQ) of rails?
Answer: The MOQ is usually 100 tons, but it can be adjusted according to customer needs. Small batch orders may involve additional fees.

2. How long is the delivery cycle of rails?
Answer: Spot goods usually take 15-30 days, and customized production takes 45-60 days (depending on the order volume and process requirements).

3. What test reports do you provide?
Answer: We provide third-party test reports (such as SGS, BV), including chemical composition analysis, mechanical properties testing (tensile, hardness), ultrasonic flaw detection, etc.

4. What is the packaging method of rails?
Answer: Usually steel strapping + anti-rust paper wrapping, or wooden boxes/containers are used for reinforcement according to customer requirements to ensure transportation safety.
