    The high-toughness ductile iron at low temperature


    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


    The high-toughness ductile iron at low temperature


    The impact strength maintains nearly the same at 0 ℃, -20 ℃ and -40 ℃ and declines at - 50 ℃, -60 ℃. It shows that the ductile iron for low temperature application performances well even at very low temperature.
