Alloy C-4 is an austenitic nickel-molybdenum-chromium alloy with a low carbon, silicon, and iron content. This alloy 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. When machined perfectly, no knife line attack occurs in the heat-affected zones of awelding edge. Alloy C-4 is characterized by: Very good resistance in a broad field of corrosive media, in particular under strongly oxidizing conditions.
Coil is a kind of metal material with corrosion resistance and high temperature resistance, due to its wide application in the manufacturing industry, coil can be divided into a variety of different classifications according to different materials and processing processes.with good corrosion resistance and heat resistance, mainly used in chemical, petroleum, electric power and other fields.
