Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

A new concept of creating steels to provide high resistance of the rolling surface of wheels to wear and damage was proposed, requirements for a set of mechanical characteristics of such steels were developed and chemical composition of steel of a new generation for railroad wheels, as well as heat treatment mode during their repair surfacing were substantiated. 15 Ref., 2 Tables, 4 Figures.
Keywords: high-strength railroad wheels, slid flat, shelled tread, wear, operational reliability
