WHITEHEART	OTHER CAST IRON

Our fittings are made of whiteheart malleable cast iron, obtained by decarburization. This heat treatment improves the metal elasticity and provides excellent ability to accept deformation under stress without cracking. .

MICROGRAPHIC OBSERVATION WITH/WITHOUT HEAT TREATMENT

HEAT TREATMENT 60 H AT 1030°C
This stage consists of removing the carbon from the upper layers of the material (decarburization). Therefore, the mechanical properties of the material are improved, especially the malleability which ensures a better breaking strength.
