Sandvik Mining and Construction

HX900 cast-in-carbidea unique wear material

� Combining the wear resistance of cemented carbide

with the impact resistance, ductility and forming

capability of nodular iron.

Sandvik Mining and Construction2

capability of nodular iron.

HX900 performance


The wear resistance is close to that of solid cemented carbide

Average strength is 80-90 % of that of nodular cast iron

HX900 CharacteristicsThat Make a Difference

� Unique combination of hardness, (wear resistance) and toughness

� Metallurgical bond between CC and matrix gives a composite material with high quality adhesion to the CC.

Sandvik Mining and Construction7

� Products can be taylor made to meet the individual customer needs− Geometry

− Placing of the carbide

− Product improvement after type of wear, change of wear

− Flexibility in using type of cc-grade

− Flexibility in using type of cc (granules, tiles, inserts)

HX900 cast-in-carbidea unique wear material

Cutting

� A wide range of applications, such as:

− mining and mineral handling industries − steel works, concrete plants− road maintenance

� The wear resistance is generally 3-15 times higher compared to

conventional wear resistant steels, castings and hardfacing

HX 900What to look for

� In general, heavy wear applications with short life

� Applications where maintenance work causes extensive production stops i.e. life are highly valued


� Applications where solid cc are too brittle

� Applications where adhesion problems occur with brazed cc connections
