Product application
Corrosion Resistant Alloy
Corrosion-resistant alloys are a type of metal materials specially designed to resist various corrosive environments (such as chemical corrosion, electrochemical corrosion, high temperature oxidation, etc.). They generally have excellent corrosion resistance and are widely used in chemical and petrochemical industries (strong acids, strong alkalis, high temperatures, high pressures, etc.), oil and gas industries (sour gas wells, offshore platforms, pipelines, etc.), marine engineering (seawater corrosion, deep-sea mining, etc.), electric power (nuclear power, thermal power, etc.), aerospace and other fields.
