Cast Iron
Cast Iron DIN EN 1561 (Meehanite)
GG25/GD250 is the most common cast iron grade. It is an iron-carbon-silicon alloy often referred to as grey cast iron. It has widespread engineering applications due to its many attractive properties which compensate for its limitations, ie low tensile strength and ductility. Some of its more attractive properties are high compressive strength, excellent machinability, good resistance to sliding wear, very good thermal conductivity and exceptionally good vibration damping and absorption properties.
Weldability is considered fair to poor as compared to low carbon steels and advice should be taken from a welding consumables supplier.
Normally supplied as cast in bar form. Cast iron is widely used in many industries to produce an array of products including cylinder blocks, gears, cam shafts, flywheels, glass moulds, hydraulic ram parts, pistons, machine slide ways, pumps, valves and rotors etc.
