60kg of heavy rail material has 50 Mn, U71Mn two kinds, length is 12,12.5 meters two kinds, the quality requirements in the production process strictly, in addition to guarantee its chemical composition, also requires testing of mechanical properties, including the drop test and acid corrosion macrostructure examination, etc. Main Application In order to meet the needs of railway reload and high speed, in addition to increasing the single weight of heavy rail,and the comprehensive performance should be improved.High toughness, abrasion resistance, crushing resistance and brittle resistance are required.The 60kg heavy rail is fully equipped with high compressive resistance, abrasion resistance and tenacity, so 60kg of heavy rail is usually laid on the main trunk line of railway transportation.
