110G13L steel is used: for the manufacture of castings of housings vortex and ball mills, cheeks and cones crushers, tram and rail switches and frogs, track Shoe, sprocket, teeth of excavator buckets and other parts operating at impact wear parts mill liners mining and metallurgical equipment; astrakhovych switch frog 1/11 and 1/9 marks to the rails of types R75, R65, R50 with cast cores.

Note

Steel vysokoorganizovannaja wear-resistant austenitic class.
The steel has a high resistance to wear when exposed to high pressures or shock loads.

Fe is the basis.
According to GOST 21357-87, to increase the wear resistance of castings, microalloying of steel with titanium up to 0.05%, vanadium up to 0.30%, molybdenum up to 0.20% is permissible.
KSt 81-038: 2009 shows the chemical composition of steel with narrower component content limits used for the manufacture of wear-resistant parts of mill lining.
In accordance with GOST 7370-98, in the manufacture of cores and cast-iron crosspoints of switches, it is permissible, with the agreement of the manufacturer and the consumer, to introduce into the steel alloying elements and modifying additives.
According to GOST 2176-77, the chemical composition is given for steel grade 110G13L. Castings may be made of steel with an increased content of carbon, but not more than 1.50%. Deviations from the norms of chemical composition are allowed: for carbon ± 0.020%; for silicon ± 0.10%; on manganese, copper, chromium and nickel ± 0.10% each; by titanium and tungsten ± 0.050% each; by vanadium, molybdenum and niobium ± 0.020% each.
