The wrought equivalent alloy to ASTM A494 Grade CW6MC is Inconel 625 (UNS N06625). It is a Nickel-Chromium-Molybdenum alloy designed for outstanding corrosion resistance across oxidizing and reducing environments, along with high strength.
CW6MC (Inconel 625) provides exceptional resistance to pitting, crevice corrosion, and intergranular attack in highly corrosive media like seawater, non-oxidizing acids, and high-chloride environments. Its high Molybdenum content (8.0-10.0%) is key to resisting chloride-induced corrosion.
Yes, CW6MC is an excellent high-temperature alloy. It retains high strength and good oxidation resistance up to 980°C (1800°F). For pressure vessel service (like valves), its maximum ASME B16.34 service temperature is typically high, demonstrating its stability in elevated heat environments.
CW6MC is the alloy of choice for extreme environments such as sour gas service (Oil & Gas), critical marine/offshore applications (seawater), flue gas desulfurization (FGD) systems, and aggressive chemical processing plants handling mineral acids.
