Jedan od najvažnijih dijelova koji se danas koriste na željeznici su dijelovi na cestovnim prijelazima preko pruge i uglavnom dinamička komponenta izložena djelovanju. Mangalloy, također poznat kao čelik s manganom ili Hadfield čelik, je čelik s legurama koje u prosjeku sadrže 13 % mangana i jedinstven je po tome što povezuje visoku žilavost i duktilnost s velikom sposobnošću radnog otvrdnjivanja. Otpornost na trošenje prije kontaktnog trošenja ovisi o intenzitetu otvrdnjavanja površine i postupku otvrdnjavanja tijekom rada [1, 2, 3,]. Budući da se zbog otpornosti abraziji povećava postotak ugljika iznad 1,4 % i više, može se pojaviti problem postizanja homogene austenitne strukture koja bi bila bez zrnaca karbida [4]. ; Nowadays one of the most important parts, which are used in railway industry, are crossings, and principally the dynamic component of the operation exposures. A Mangalloy, also called as manganese steel or Hadfield steel, is a steel with alloys containing an average 13 % of manganese and is unique for the reason that it combines high toughness and ductility with great work-hardening capacity. The wear resistance before the contact wear depends on the level of the surface hardening intensity, and the hardening process during operation consequently [1, 2, 3]. As abrasion resistance is proper to increase the carbon level above 1,4 % and moreover, it could cause a problem in obtaining a homogenous austenitic structure which would be sufficiently free of carbide bordered grains [4].
