The most up-to-date trends in stainless steel production—aiming at the reduction of production costs—consist of the substitution of steel scrap by hot metal, coming from the reduction of iron-chromium ores. This process requires a more extensive dephosphorization. The dephosphorization process, when applied to chromium steels, requires slag with high dephosphorization properties, as either ...

INVESTIGATION OF DUCTILE IRON IN MOLD

2015-3-3  Ductile iron was first developed in 1943 and it is widely used in automotive industry. The difference between cast iron and ductile iron is due to the presence of spheroid graphite in the matrix of ductile iron which is not found in brittle cast iron. Ductile iron possesses higher ductility and tensile strength than in cast iron.

Ductile iron has been suggested as a candidate material for a number of practical applications, including turbine castings, automotive components, and transportation and storage casks for hazardous and radioactive materials. The applications require the enhanced ductility resulting from the presence of spherical graphite nodules in the ductile ferrite iron matrix.
