Description

120Г13Х2БЛ 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.

Note

Wear resistant austenitic steel. Steel has high resistance to deterioration when exposed to high pressures or shock loads. Steel has a high resistance against abrasive wear and high cold resistance.
