Inconel 718 vs 825 Round Bars
Inconel 718 round bars offer exceptional high-temperature strength and fatigue resistance (up to 700°C), making them ideal for aerospace and turbine applications. Incoloy 825 bars (often simply referred to as 825) offer superior resistance to acid corrosion and chloride stress cracking, making them ideal for the chemical and oil and gas industries. Inconel 718 round bars are precipitation hardened, resulting in high strength (tensile strength 130-220 ksi), while alloy 825 bars are typically used in the annealed state, resulting in lower strength.
Is Inconel 825 magnetic?
The primary factors determining the applications of this alloy are its strength and heat resistance, not its magnetism. - Inconel 825: Inconel 825 contains iron, but in a lower amount than Inconel 600. Like other high-nickel alloys, it is generally considered non-magnetic.
Inconel 718 round bars offer greater flexibility and strength than other alloy grades. They are hardened through high-temperature quenching. They exhibit excellent weldability and superior resistance to fracture and creep, contributing to the alloy's strength and durability. Inconel 718 round bars remain stable at both high and low temperatures. These Inconel 718 round bars possess exceptional resistance to oxidation, corrosion, and stress cracking. These seamless and welded tubings have a tensile strength of 130,000 psi and a yield strength of 75,000 psi.
Similarly, Inconel 825 round bars offer excellent corrosion resistance and are widely used in large-scale industrial applications such as petrochemicals, power generation, aerospace, and oil and gas. These round bars are commonly used in the manufacture of various equipment. These round bars offer interchangeable properties. The alloy has a tensile strength of 80,000 psi and a yield strength of 32,000 psi. The estimated suitable temperature for these bars is 1020°C.
