90RA rail is a type of railway track steel rail that adheres to the standards set by the American Railway Engineering and Maintenance-of-Way Association (AREMA). It is commonly used in railway transportation systems, particularly in the United States and other countries that follow AREMA standards.
The 90RA rail is made from high-quality carbon steel, which provides it with excellent strength and hardness. The standard dimensions of the rail are 90 pounds per yard (approximately 45 kilograms per meter) in weight, 130.2 millimeters in bottom width, 142.9 millimeters in height, and 12-25 meters in length. It also features a specific head shape and profile design that ensures stability and smoothness during operation.
One of the key advantages of the 90RA rail is its excellent wear resistance and impact resistance, which make it suitable for heavy loads and high-speed operations. Additionally, it has good welding and processing properties, making it easy to install and maintain.
The 90RA rail is widely used in various railway transportation systems, including mainline railways, mining railways, industrial railways, and more. Its versatility and durability make it an ideal choice for railway operators who require reliable and long-lasting track infrastructure.
In terms of manufacturing process, the production of 90RA rail involves several steps, including steelmaking, rolling, heat treatment, and finishing. High-quality raw materials are selected and melted in a furnace before being rolled into the desired shape and size. The rail is then subjected to heat treatment processes such as quenching and tempering to enhance its mechanical properties.
To ensure the quality and safety of the 90RA rail, rigorous testing and inspection procedures are carried out at various stages of production. These tests include non-destructive testing methods such as ultrasonic testing, magnetic particle testing, and radiographic testing, as well as destructive testing methods like tensile testing and bend testing.
Overall, the 90RA rail is a high-performance railway track steel rail that offers excellent durability, reliability, and performance. As a Chinese supplier, we can provide high-quality 90RA rail and other types of railway track products to meet the needs of different customers. If you are interested in learning more about our products or obtaining a quote, please feel free to contact us.
It is worth noting that the 90RA rail is often used in conjunction with other railway track components such as fishplates, bolts, and fasteners to create a complete and secure track system. The selection of these components is critical to ensuring the safe and efficient operation of the railway system.
In addition, the installation and maintenance of the 90RA rail must be carried out by trained and experienced professionals who follow strict safety protocols and guidelines. Regular inspections and maintenance are necessary to identify any potential issues and prevent accidents or derailments.
Overall, the 90RA rail is a crucial component of modern railway transportation systems, and its quality and performance play a vital role in ensuring the safety and efficiency of railway operations. As a leading supplier of railway track products, we are committed to providing our customers with the highest quality products and services to meet their needs and exceed their expectations.

Standard EN 13674 - 1:2003 consists of two main parts:

− qualification test and acceptance tests

Qualification tests are some other tests that were previously carried out, as for example, fracture toughness. Acceptance tests characterize the properties of the prescribed tests, which ensure production of high quality rails, and testing requirements of railway administration.

Quality of rails is based on measured values of hardness, by which they introduced new labels for steel rails.

Qualifying tests

Qualification testing must be conducted at least one in five years and the major

changes in technology, production rails. Additional testing residual stresses are carried

out on all types of steel rails every two year maximum, provided that the longitudinal

strain rate in the rails can amount to up to 250 MPa.

The prescribed qualifying examination is the following:

− fracture toughness

− fatigue crack growth rate

− fatigue testing

− residual stress in rail foot

− variation of centre line

− tensile strength and elongation

− segregation

− other qualification requirements

Acceptance tests

Within acceptance testing is carried out a series of laboratory tests such as:

− chemical composition (the maximum content of the following elements: H, O, Al, V, N and oligo elements)

− microstructure (increasing x 500)

− degree of decarburizing charred layer (allowed up to 0.25 mm)

− purity of steel (especially the presence of oxide)

− macrostructure (Baumann test)

− hardness

− tensile strength

Other acceptance testing rails are:

− dimension tolerances

− criteria (control template)

− inspection requirements / tolerances for to internal quality and surface quality

Internal state is examined ultrasound in a continuous process control, and includes at least 70% of the head and at least 60% web.

- Standard of UIC 860 V: 1996 - prescribed four types pearlite steel rails in the range of tensile strength from 700 to 1300 MPa.

- Standard EN 13674 - 2003, provides seven types pearlite steel hardness in the range 200 to 390 HBV, types steel in accordance with EN 13674, based on the values of hardness (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
