VDM® Alloy C-4 is an austenitic nickel-molybdenum-chromium alloy with a low carbon, silicon, and iron content.
VDM® Alloy C-4 has a significantly lower tendency to form precipitation in the temperature range between 650 and 1,040 °C (1,202 - 1,904 °F), improving its resistance to inter-crystalline corrosion.
Due to the combination of chromium with a high molybdenum concentration, VDM® Alloy C-4 has an extraordinary resistance to a number of chemical media: e.g. contaminated, reducing mineral acids. Due to its high nickel concentration, VDM® Alloy C-4 is practically insensitive to chloride-induced stress corrosion, including in hot chloride solutions.
Typical applications for VDM® Alloy C-4 are:
VDM® Alloy C-4 is used in a field of chemical process technology, including at higher temperatures.
Special applications are:
