Inconel 690 Bars

Inconel 690 Bars

Inconel 690 Bars are a high performance nickel chromium based super alloy with excellent oxidation resistance, high temperature strength and long term durability. The alloy consists primarily of nickel (58–63%), chromium (28–31%), and small amounts of iron, and is highly resistant to high temperature oxidation and scaling. Inconel 690 is engineered for harsh environments and is used in power generation, nuclear reactors and chemical processing industries. Its special properties allow it to work reliably under extreme thermal and mechanical stresses and is therefore preferred for using components that require high strength and resistance to thermal fatigue.

Chemical Composition of Inconel 690 Bars

The composition of the Inconel 690 bars is crucial for understanding its properties and performance in various industrial applications.

Inconel 690 Bars FAQ's  

Inconel 690 Bars Start From Rs. 150/Kilogram To Rs. 200/Kilogram.

Yes, Inconel 690 is a nickel-based alloy that has excellent corrosion and oxidation resistance. It's especially resistant to chloride-ion stress corrosion cracking and pitting, making it a great choice for use in chemical processing and other highly corrosive environments.

No, Inconel 690 is an austenitic nickel-based alloy that has low magnetic permeability. This makes it ideal for use in applications where electrical or thermal properties are required and a magnetically susceptible material could interfere with operation.
