Our GH1140 superalloy strip is built to handle the toughest industrial environments, delivering unbeatable strength and oxidation resistance where extreme heat is the norm. This nickel-iron-chromium alloy is a game-changer for high-temperature applications, and we’re here to show you what makes it stand out, how it fits into industry trends, and why our product is the top choice for your projects.
What is GH1140 Alloy?
GH1140 is a nickel-iron-chromium superalloy designed to thrive in blistering heat and harsh conditions. With a robust mix of nickel, iron, and chromium, it forms a protective oxide layer that shrugs off oxidation and corrosion, performing reliably up to 850°C (and hitting 1000°C for short bursts). Its high creep resistance and tensile strength make it perfect for industrial components like furnace parts, heat exchangers, and turbine components. Our GH1140 strips are precision-rolled to ensure uniform thickness and a smooth surface, ready for the most demanding applications.
We craft our strips with advanced manufacturing techniques, and the alloy’s heat-treatable nature lets us fine-tune its strength and toughness to meet your specific needs, whether for new builds or component repairs.
Industry Applications
Our GH1140 strips are a powerhouse in industrial settings, driving components like furnace linings, heat exchangers, and petrochemical reactors that face intense heat and stress. Its oxidation resistance and durability make it a go-to for power generation turbines and aerospace parts like combustors. You’ll also find it in chemical processing and oil and gas systems, where high temperatures and corrosive environments demand top performance. The strip’s versatility makes it ideal for both manufacturing new parts and extending the life of worn components through repairs.
