High alloy manganese steel is preferred for the production of chain tracks for tractors and other chain machinery, linings for
ball mills, crushers and facing plates for jaw crushers,
hammers and facing plates for rotor crushers, cones - movable and fixed as well as pressing bushings for cone crushers used in mining, coal and cement industries. We
also manufacture high wear-resistant details for excavators, bucket loaders, backhoe loaders,
bulldozers and graders, which work under impact loading, as well
as spare parts upon customer requirements.

Carbon non-alloy steel is used for the production of
spare parts for tractors and agricultural machinery, plough-corps, ploughshares, bearing rollers, single or double-board
wheels, out span (pillow-block) corps, couplings, rollers
for poly-paste, etc. We also produce ploughs for pre-sowing
and deep furrow.
