Train rails: Mechanical properties
In the following table we show you the mechanical properties of the train rails manufactured by ArcelorMittal. In the table we indicate the standards along with grades of steel and mechanical properties: Rm MPa, min A5% and HB.
You can see information for the standards UIC 860 – 0 1986 – 2008, EN 13674 – 1 2006, EN 13674 – 1 2006, BS 11 1965, AREMA 2006, AREMA 2007 and AS 1085.1 2002
