Heavy rail is a kind of steel with nominal weight greater than or equal to 30kg/m, which requires higher strength and toughness, wear resistance, crushing resistance and brittle fracture resistance. The quality of the production process is strictly required. In addition to ensuring its chemical composition, mechanical properties, drop hammer test and acid etched macrostructure test are also required. Heavy rail mainly used for 20-50 tons of traveling, crane, crane special track; and power plant coal feeder, etc.
