Rails for railway transport are made of carbon steel. The quality of rail steel is determined by its chemical composition, microstructure and macrostructure.
Rolled steel hot–rolled square is a metal product used for reinforcement of reinforced concrete structures.
Railway rails of the R-18 type
Railway rails of the R-18 type are rails designed for laying on narrow gauge railways. The rails are of normal hardness and are made of semi-quiet steel N50ps. These rails are designed for underground transport of the mining and coal industry.
Railway rails of the R-24 type
Railway rails of the R-24 type are rails designed for laying on narrow gauge railways. The rails are of increased hardness and are made of calm PT70sp steel. These rails are designed for underground transport of the mining and coal industry.
Railway rails of the R-43 type
Railway rails of the R-43 type are rails designed for link and without a joint track of broad gauge railways. The rails are made of 70 steel. These rails are designed for industrial transport tracks.
