Abstract
In this paper combined Hadfield steel - stainless steel - rail steel compounds are considered. Structural studies and estimation of mechanical properties showed that using an intermediate layer of low-carbon steel with 0.2 C wt. % and 5-20 mm thick between high-carbon steel and chromium-nickel steel in the formation of welded joints increases the reliability of connections by reducing the amount of high-strength zones as compared to compounds without a barrier layer.
