What Are Railroad Spike Made Out Of

Railroad spikes are a common type of rail fastener used to connect steel rail and railway sleeper. There are many types of spikes, including screw spikes and dog spike. According to its structural characteristics and uses, it can be divided into four categories.

 

Ss series Sleeper Screw: Ss 1/130, Ss 1/150, Ss 2/180, Ss 5/150, Ss 6/150, Ss 7/180, Ss 8/140, Ss 8/150.

Square head screw spike: UIC, AREMA, DIN, GB or According to your drawings or samples.

Hexagon screw spike: several different sizes such as:M22*145, M22*155, M22*165, M22*185, M22*195, and so on.

Double-head screw spike: two-end-head screw spike is always used with Nabla clip fastening system, especially popular used in Africa.

 

 

Common materials for railway spikes

 

Basically railroad spikes are made out of the following materials: Q235 carbon steel, Q 345B carbon steel, Q345D carbon steel, 45# (GB standard) carbon steel, 40Cr steel, 35CrMoA steel and 20MnTiB.

 

The differences of the material that used for making railroad spikes:

 

 

Q235 carbon steel: it features in good plastic property, toughness and welding performance. It also has good cold pressing and bending. The Q235 carbon steel is always used for parts and welding structure application with average requirements.

 

45# carbon steel: it is the most used medium carbon steel. Good comprehensive mechanical properties. It is easy to crack in cold pressing.

 

Q345 carbon steel: Good comprehensive mechanical properties, good processing performance with cold and hot pressing. Good corrosion resistance.

 

40Cr steel: after conditioning, it has good comprehensive mechanical properties, toughness in low temperature impact. Poor welding property, easy crack. It is one of the most used steel.
