HARDENABILITY OF STEEL FOR HIGH-STRENGTH RAILS

O PROKALIVAYEMOSTI STALI DLYA VYSOKOPROCHNYKH REL'SOV

The important technical property of hardenability of rail steel is reviewed from the standpoint of increasing rail efficiency and its endurance. The efficiency of rails can be assured by increasing the contact fatigue strength of the steel by means of heat treatment. Thermal treatment results in a homogeneous structure of sorbite in the rail head at depths affected by contact stresses. Comparisons are made using data concerned with rail end hardenability according to GOST 5657-59, which involves quenching or tempering in oil of the rail heads to establish a standard. It is concluded that sufficient hardness of the rail can be obtained by complex alloying of the steel to a general content of about 3 percent.
