|Designation GOST Cyrillic||130Г14ХМФАЛ|
|Designation GOST Latin||130G14XMFAL|
|By chemical elements||130Mn14CrMoVN|
130G14KHMFAL steel is used: for the manufacture of casting parts housings vortex and ball mills; cheeks crushers; tram and rail switches and crossings; track Shoe; stars; teeth of excavator buckets and other parts operating under conditions of impact wear.
Steel wear-resistant austenitic class. The steel has a high resistance to wear when exposed to high pressures or shock loads high resistance against abrasive wear, high cold resistance. Steel retains a high value of impact strength in the hardened state (in the process of operation of parts).
