Types of Inconel Material
What is an Inconel Alloy?
Inconel is a family of austenitic nickel-chromium superalloys, typically 50–72% nickel and 14–25% chromium, developed for service where heat, pressure and corrosion act together. Inconel is a registered trademark of Special Metals Corporation; equivalent alloys are produced worldwide to ASTM, ASME and DIN specifications. These alloys maintain their strength and structural integrity in extreme environments, making them ideal for high-temperature and high-pressure applications. Inconel alloys are engineered to resist stress-corrosion cracking, pitting, and chemical attacks, even in the presence of caustic substances.
