# Alloy 80A (UNS N07080) – High-Performance Nickel-Chromium Alloy for Extreme Environments
Alloy 80A, also known by its UNS designation N07080, is a high-performance nickel-chromium alloy specifically designed to withstand extreme environments. This superalloy combines excellent mechanical properties with outstanding resistance to oxidation and corrosion, making it a preferred choice for demanding applications across various industries.
The unique properties of Alloy 80A stem from its carefully balanced chemical composition:
Alloy 80A maintains excellent tensile and creep strength at elevated temperatures, with typical tensile strength ranging from 800 to 1000 MPa at room temperature.
The high chromium content provides outstanding oxidation resistance at temperatures up to 1100°C (2012°F), making it suitable for high-temperature applications.
Alloy 80A demonstrates superior resistance to various corrosive environments, including sulfur-containing atmospheres and carburizing conditions.
Due to its exceptional properties, Alloy 80A finds applications in several critical industries:
Alloy 80A can be fabricated using standard techniques, though it requires special considerations:
