What kind of steel are rails made of?

Steel rails are a core component of railway tracks, providing the essential function of guiding train wheels while transferring enormous loads to the sleepers. Choosing the right steel rail material is critical for safety, durability, and performance. GNEE RAIL supplies a wide range of steel rails-including crane rails, heavy rails, and light rails-as well as other railway fasteners and accessories. Understanding the types of steel used for rails helps rail operators select the right products for different track environments.

 

What kind of steel are rails made of?

 

Rails are primarily made of high-strength, wear-resistant steels. For heavy-duty applications such as crane rails (QU70–QU120) and heavy rails (50–75kg/m), manganese-carbon steels like U71Mn are the industry standard. U71Mn offers high tensile strength, excellent toughness, and good wear resistance, making it suitable for concentrated loads and industrial environments. Higher-grade rails like U75V or European R350HT steel are used for high-speed or extremely heavy load lines.

 

 

Steel Grade	C (%)	Si (%)	Mn (%)	Tensile Strength (MPa)	Elongation (%)	Hardness (HB)	Typical Application
U71Mn	0.65–0.76	0.15–0.35	1.10–1.40	≥880	≥9	240–270	Heavy Rail / Crane Rail
U75V	0.71–0.80	0.50–0.80	0.70–1.05	≥980	≥9	240–270	High-Speed / Heavy Rail
50Mn	0.48–0.56	0.17–0.37	0.70–1.00	≥645	≥13	–	Medium Rail
Q235	0.12–0.20	≤0.3	0.3–0.7	375–460	≥26	–	Light Rail / Industrial Tracks

 

How Do Heavy Rail and Light Rail Standards Differ Across Countries?

 

Rail standards vary internationally, reflecting differences in load requirements, climate, and operational conditions. GNEE RAIL provides rails that comply with UIC, AREMA, BS, DIN, JIS, and GB standards, ensuring compatibility with local and international projects. For instance, UIC60 rails are commonly used in European high-speed lines, while ASCE 60 or 75 rails meet American heavy rail requirements.

 

 

Standard	Rail Type	Weight (kg/m)	Material	Typical Application
GB2585-2007	Heavy Rail	50–75	U71Mn / U75V	Chinese high-speed & heavy-load lines
UIC860	Heavy Rail	50–60	900A/1100	European mainline tracks
AREMA / ASCE	Heavy Rail	60–136	U71Mn	American freight & industrial tracks
JIS E 1103	Light / Medium Rail	15–50	Carbon steel	Japanese industrial & passenger lines
GB11264-89	Light Rail	6–30	Q235 / 55Q	Urban transit & light industrial
