U71Mn is a pearlite rail steel containing manganese. "U" stands for rail, 71 indicates an average carbon content of 0.71%, and Mn indicates that it contains manganese. This combination of ingredients gives it excellent comprehensive performance. The addition of manganese effectively improves the strength and toughness of the stål, så att U71MN -skenor har hög draghållfasthet och god slagmotstånd och tål ofta rullning och påverkan av tåghjul.

U71Mn rails have moderate surface hardness and outstanding wear resistance through reasonable rolling process and heat treatment, which can significantly reduce the wear caused by wheel rolling friction and extend the service life of rails. At the same time, it also has a certain anti-peeling performance, which can reduce the probability of cracks, peeling and other diseases on the surface of the rails, and ensure the safety and stability of train operation .

In actual applications, U71Mn rails are often used in general trunk railways, urban rail transit and other lines. These lines have large passenger and freight volumes, and have high requirements for the bearing capacity and wear resistance of rails. With its own advantages, U71Mn rails can effectively cope with the pressure and wear caused by train operation, reduce maintenance frequency, and reduce railway operating Kostnader . Oavsett om det är en hektisk passagerarlinje eller en tung belastning frakt järnväg, ger U71MN-skenor en solid garanti för effektiv och säker drift av järnvägstransporter med deras pålitliga prestanda .}
