Inconel 718

Inconel 718 is a high-performance nickel-based superalloy widely used in aerospace, defense, and power generation. Dong-A Special Metals Co. highlights its value as both a structural material and a recyclable resource.


Key Characteristics and Applications

Inconel 718 consists of nickel (Ni), chromium (Cr), iron (Fe), niobium (Nb), molybdenum (Mo), aluminum (Al), and titanium (Ti). This combination results in exceptional strength, corrosion resistance, and high-temperature stability. Its excellent weldability and formability make it ideal for manufacturing large and complex components.


The alloy maintains over 1,200 MPa of ultimate tensile strength (UTS) and over 1,000 MPa of yield strength (Y.S.). It exhibits superior resistance to creep, fatigue, and high-temperature oxidation. After stress-relieving treatment, it achieves enhanced machinability and reduced distortion, critical for high-precision rotating parts such as turbine shafts, discs, and spindles.


In the aerospace industry, Inconel 718 is extensively used in turbine disks, combustor components, compressor parts, and exhaust nozzles. It also plays a vital role in gas turbines, nuclear reactors, offshore rigs, and high-pressure chemical and energy systems.


Strategic Recycling and ESG Benefits

As a precipitation-hardened superalloy, Inconel 718 contains valuable metals like nickel and chromium. These elements make scrap recycling economically viable and environmentally beneficial. Recycling methods include remelting and powdered metal processing of industrial waste and machining scrap.


Dong-A Special Metals Co. applies advanced surface treatment and remanufacturing technologies to recycle Inconel 718 efficiently. This ensures a stable raw material supply, reduces reliance on imports, and supports ESG (Environmental, Social, and Governance) goals.


Furthermore, converting solid machining scrap into powder feedstock supports additive manufacturing (AM), a key solution in sustainable industrial practices. This recycling-AM synergy enables high-efficiency production and optimal resource circulation.


Dong-A Special Metals is committed to supporting CNC, aerospace, and turbine industries with premium-grade recycled materials that ensure performance and sustainability.
