Heavy Rail of P50/R50 Rails

P50 rails, also known as GOST R50 rails, are heavy-duty rails with high load carrying capacity and compression resistance, and are commonly used in high-speed railways and heavy transportation lines. It is commonly used in high-speed railroads and heavy transportation lines.P50 rails comply with the Russian standard GOST, commonly used materials are 50Mn or U71Mn, the weight of each meter is about 51.514 kilograms, and the standard length is 12.5 meters, which is in accordance with the GB2585-2007 standard.

Other Notable Features:

High Tensile and Bending Strengths:P50 rails have a high ultimate tensile strength (≥500 MPa) and bending strength (≥420 MPa).

High Elongation:They also possess a minimum elongation of 14%, contributing to their durability and ability to withstand repeated stresses.

Durable and Reliable:P50 rails are commonly used on high-speed and heavy-haul railway lines to ensure the reliability and durability of railway systems.

Dimensional Accuracy and Uniformity:These rails are known for their excellent dimensional accuracy, straightness, and uniformity, which contribute to smooth train movement and reduced noise and vibration.

Heavy-Duty Design:They are designed for heavy loads and are used in various applications, including rail transportation, slide rails, temporary transportation paths, and industrial frameworks.

Railway Track Systems:P50 rails are commonly used in conjunction with rail joint bars or fishplates to provide secure and stable connections between rails.

Bull Headed Profile:P50 rails often feature a bull-headed profile, where the head is larger than the foot, providing increased strength and allowing for better wear resistance.
