Special melting further improves the cleanliness of steel and the homogeneity of steel quality. High-cleanliness materials created through atmosphere melting are used as base materials for 15 t ESR and 5 t VAR. *The manufacturing process once ingots are created

is the same as with special steel bars and tubes.
