Gnee Steel is a professional manufacturer of Inconel 718 products. Gnee Steel's 718 alloy products are packaged in various ways, including: steel strapping: pipes with an outer diameter not exceeding 3 inches are typically bundled together with polypropylene film to prevent rusting during sea transport, then secured with steel straps; wooden crates/crates: pipes are usually packaged in wooden crates or crates for protection during transport, especially for longer or larger diameter pipes; seaworthy export packaging: suppliers typically use standard seaworthy export packaging methods, which may include various materials and techniques to protect the pipes during transport; and tarpaulin packaging: to prevent rainwater, seawater, etc., from seeping into the export wooden crate packaging during transport. Gnee Steel specializes in the production and sales of alloy materials. Gnee Steel's products are widely used in aerospace, chemical, power, automotive, and nuclear energy fields, and customized alloy material solutions can be provided according to customer needs.

UNS N07718 Incon Nickel Alloy Product Encyclopedia
UNS N07718 Incon Nickel Alloy Product Encyclopedia
Inconel 718 alloy (UNS N07718, Werkstoff 2.4668) is a high-quality precipitation-hardening nickel-chromium superalloy with high strength, excellent corrosion resistance, and outstanding creep rupture properties at temperatures up to 700°C (1300°F). Due to its unique ease of machining and welding, and its resistance to post-weld cracking, it is arguably the most widely used nickel-based superalloy, especially in the aerospace and oil and gas industries.
What are the applications of Inconel 718?
Inconel 718 is a commonly used nickel-based superalloy, widely used in the aerospace, automotive, and energy industries due to its excellent thermomechanical properties. However, it is also notoriously difficult to machine due to its short tool life and low machining efficiency.
