UNS N06600 AMS 5540 Strip

Uses of Inconel 600 

As per UNS N06600 AMS 5540 Strip Manufacturer, Inconel 600 is used widely in the chemical industry, thanks to its strength and high corrosion resistance. Typical uses in this industry include heaters, stills, bubble towers, and processing condensers for fatty acids as well as tube, tube sheets, and flaking trays for producing sodium sulfide and for equipment handling abietic acid in producing pulp and paper goods. When heated, Inconel alloys form a thick yet stable oxide layer, which protects surfaces from increased attack.

Alloy 600 is also used in many applications in the heat-treating industry. The alloy’s strength and corrosion resistance at high temperatures make it ideal for furnace components, including mufflers, retorts, roller hearths, and heat-treating baskets and trays. Plus, Inconel 600 is used in aeronautics for engine and airframe components that need to withstand high temperatures like lockwire, turbine seals, and exhaust liners.

Alloy 600 is standard construction material in building nuclear reactors. It provides excellent corrosion resistance by high purity water, with no indication of chloride-ion stress-corrosion cracking in reactor water systems. Inconel 600 is produced to exacting specifications for nuclear applications and is referred to as Inconel 600T.

Machining and Working Instructions for Inconel Alloy 600

Alloy 600 is machinable into complex shapes, like pipe fittings, flanges, and valve parts. The main machining/cutting methods are drilling, boring, turning, grinding, and milling. This alloy is best machined using heavy-duty equipment and cutting tools large enough to withstand the loads and heat generated by the process. Tools must be sharp and have the correct geometry. The alloy is slightly more machinable than Type 304 stainless steel but slightly less machinable than type 303 free-machining stainless steel.

General machining characteristics of Inconel 600 include

• Large cutting forces and high cutting temperature, usually 1.5~2 times than carbon steel.
• The serious wear of cutting tools results in a very short service life.
• Serious work hardening during the machining.
• Very difficult to dispose of the chips during the machining process.

Several factors impact the alloy’s behavior during heating. These factors include the amount of cold work, grain size, chemical composition, and material dimensions. As a result, times and temperatures for heat treatment are generally experimentally determined. This alloy needs to be cleaned before it is heated in a sulfur-free atmosphere. Furnace atmosphere for forging and open annealing need to be slightly reducing to stop excessive oxidation. Inconel 600 can be bright-heated in a vacuum or dry hydrogen. Pickling is required for a bright surface.
