Cast iron is an essential component of industrial products thanks to its versatility, economic efficiency and recyclability.
Cast iron is an iron-carbon material which combines many features such as vibration damping and long lifecycle as a result of various conditions and graphite formations. Datum manufactures two cast iron types:
GREY CAST IRON
Grey cast iron can be recognized from the graphite lamellae which are evenly distributed in the structure. Its assets are:
elevated damping capability
high corrosion resistance
The current manufacturing processes and the material diversity are adapted to the requirements of up-to-date technology and use. Items made of grey cast iron are used for example in heavy elements, as machine supports, gear wheels and gear boxes, pinch rolls and belt pulleys, body housings and posts, motor and cylinder blocks of combustion engines, brake discs, brake cylinders, furnace parts, pipes and pipe fittings and other rotation-symmetrical items.
SPHEROIDAL GRAPHITE CAST IRON
In ductile cast iron, the graphite contained in the liquid iron is transformed into a spheroidal/nodular shape by a magnesium treatment.
material properties similar to steel
high tensile strength and high elongation
These advantages reveal themselves in particular in cases of dynamic stress, where distortions would lead to the failure or even fracture of the component. Apart from many areas of use that are shared with grey cast iron, the ductile material is also found in punching tools, body housings, engines and drive components, turbo charger housings, diffusors, in plant and machine construction, pipes, pipelines, fittings and valves such as shut-off gate valves and butterfly valves,hydrants etc.
