The high-toughness ductile iron at low temperature
QT400-18AL(-40℃)
According to the experience of developing the produce for Linde Co. (ductile iron
supporting arm) and through the strict control of raw materials, chemical composition,
melting temperature, spheroidizing treatment, inoculation, etc., the low temperature(-40
℃) toughness ductile iron has been successfully developed. The properties achieved
from the trial production for more than 20 batches are shown in the following table
