Inconel 600/N06600/ASTM UNS/W.Nr. 2.4816/DIN/Alloy bar

Inconel 600 bar, also known by its various designations UNS N06600, W.Nr. 2.4816, and complying with standards like ASTM and DIN, is a widely used nickel-chromium alloy in bar stock form. This solid-solution strengthened material is prized for its excellent resistance to high temperatures, corrosion, and oxidation, making it a fundamental choice for machinists and engineers fabricating components for demanding environments in aerospace, chemical processing, and thermal applications.

Understanding the Alloy: Inconel 600 Explained

Inconel 600 is a nickel-chromium-iron alloy designed for use from cryogenic temperatures up to about 1175°C (2150°F). Its high nickel content provides resistance to reducing environments and caustic alkalis, while the chromium offers protection against oxidizing atmospheres. The alloy also maintains good mechanical properties and resists chloride-ion stress-corrosion cracking, making the bar stock form ideal for machining into shafts, valves, fasteners, and furnace components.

Key Applications for Inconel 600 Bar Stock

Machined from bar stock, Inconel 600 components are essential in many high-performance industries. Common uses include furnace components (radiant tubes, muffles, baskets), chemical and food processing equipment (reactor vessels, transfer piping, bubble caps), aerospace components (engine bleed air ducts, thermal insulation blankets), electrical and electronic parts (heating element sheathing), and nuclear reactor components (control rod parts, core support structures).

Machining and Fabrication of Inconel 600 Bar

Inconel 600 bar is machinable using methods suitable for austenitic alloys. It work-hardens rapidly, so successful machining requires sharp tools, rigid setups, and positive feeds. Recommended practices include using carbide or high-speed steel tools with positive rake angles, moderate speeds, and heavy, consistent feed rates to ensure the tool cuts beneath the work-hardened layer. Copious amounts of coolant are necessary to dissipate heat.

Reference Pricing and Selection Factors for Bar Stock

The price of Inconel 600 bar from Shanghai NC Metal Materials Co., Ltd. is influenced by dimensional factors, purchase volume, market conditions for nickel, and specific processing requirements. Prices are typically quoted per kilogram or per piece.
