Inconel 690 Strip Supplier

In extremely high temperature and corrosive environments, the stability of material properties is crucial. Inconel 690 alloy strip has become an ideal choice for high-end industrial fields such as aerospace, chemical industry, and nuclear energy due to its excellent oxidation resistance, high temperature resistance, and excellent mechanical properties.
Inconel 690 is a nickel-chromium-based superalloy with a chromium content of up to 27-31%, which allows it to form a dense chromium oxide (Cr₂O₃) protective layer in a high temperature environment, effectively resisting oxidation, sulfidation, and carburization. Even at extreme temperatures above 1000°C, it can still maintain excellent oxidation resistance, far exceeding ordinary stainless steel and heat-resistant steel.
In addition, the high nickel content (≥58%) of Inconel 690 alloy strip gives the material excellent high-temperature corrosion resistance, especially suitable for strong acid, strong alkali and molten salt environments. In the nuclear industry, Inconel 690 can withstand high-temperature and high-pressure steam corrosion for a long time and is the preferred material for steam generator pipes.
Through advanced cold rolling and heat treatment processes, we can accurately control the tensile strength and hardness of Inconel 690 strip to adapt to different application scenarios.
