Chinese Standard 75kg railroad steel heavy rail

TB/T 2344.1-2020 is Chinese national standard that specifies the technical requirements for 75 kg/m steel rails used in railway applications. This standard provides guidelines for the material properties, manufacturing processes, testing methods, and quality assurance for heavy rails, specifically designed for use in railway infrastructure.

Weight and Dimensions:

The rail weighs 75 kilograms per meter, which indicates its suitability for heavy loads and high-speed applications. The standard also specifies the dimensions of the rail, including height, base width, and web thickness.

Material Properties:

The standard outlines the material requirements for the steel used in the production of the rails, including the chemical composition and mechanical properties. This ensures that the rails have the necessary strength, toughness, and resistance to wear.

TB/T 2344.1-2020 describes the manufacturing processes for producing the rails, including the methods of forging, heat treatment, and finishing. These processes are crucial for achieving the desired material properties and performance.

The standard specifies various testing methods to evaluate the mechanical and physical properties of the rails. This includes tests for tensile strength, yield strength, elongation, impact resistance, and hardness.

The standard emphasizes quality control measures throughout the manufacturing process to ensure that the rails meet the established specifications and performance criteria.

75 kg/m railroad steel heavy rail is primarily used in heavy freight rail systems, where it can withstand high loads and provide stability and safety for rail operations.

Adhering to TB/T 2344.1-2020 ensures that the steel rails meet the required safety and performance standards, which is critical for the reliability and efficiency of railway systems.
