GOST 7173-54 P43 steel rail

GOST 7173-54 P43 steel rail is same as Chinese standard P43 steel rail, usually be used for mining railroad or port lifting track, we always have stock, can deliver it timely, but normally the length is 12.5m, material is U71Mn or 50Mn. If you load it by container, should cut to 12m and drill hole again.

The normal materials as below:
We can design railroad line as your requirement, and can build mining railway line and crane moving line, also can supply the all workable fasteners.

GOST 7173-54 is a standard for steel rails used in railway systems, including the P43 steel rail. The standard specifies the requirements for the manufacturing, dimensions, and mechanical properties of P43 rails.

GOST 7173-54 P43 steel rail are heavy-duty rails commonly used in mainline railways, industrial tracks, and high-speed rail systems, particularly in Russia and other former Soviet countries. They are made of high-quality carbon steel with a pearlitic structure, which provides excellent strength, wear resistance, and durability under heavy loads and high speeds.

According to GOST 7173-54, the P43 rail has the following specifications:

– Profile: The rail has a standard profile with a head width of 152 mm, a head height of 76 mm, and a web thickness of 17.6 mm.
– Length: The standard length of the rail is 12.5 meters, but it can also be supplied in shorter or longer lengths as required.
– Chemical composition: The steel used for P43 rails has a specific chemical composition that includes carbon, manganese, silicon, phosphorus, sulfur, and other elements in certain proportions.
– Mechanical properties: The rail must meet specific mechanical properties, including yield strength, ultimate tensile strength, hardness, and impact toughness, to ensure its performance and reliability under heavy loads and high speeds.

The GOST 7173-54 standard also specifies testing methods and acceptance criteria for P43 rails, including non-destructive testing techniques such as ultrasonic testing and magnetic particle inspection, to ensure their quality and safety. Overall, GOST 7173-54 P43 steel rail is a high-performance rail type that is suitable for demanding applications where high speeds, heavy loads, and long service life are critical factors. It is widely used in railway systems that require robust and durable track infrastructure to support heavy traffic and ensure safe and efficient operations.
