A buyer might call for an alloy by name, but when ordering that can translate to three separate production lines; an ASTM B168 plate or sheet, an ASTM B163 heat exchanger tube, an ASTM B167 pipe, or an ASTM B166 round bar. Same name but a real sourcing risk due to a difference in size checks, test records and packaging required.
Special Metals identifies INCONEL alloy 600 by UNS N06600, Werkstoff 2.4816, and specifies the alloy in a bulletin on its use in furnace and heat-treating equipment, where oxidation and high temperatures are the major concerns. TiAlloy begins all of its nickel alloy quotes with this identification.
Furnace and heat-treating applications include a reference to Inconel 600 / UNS N06600 in a patent for the use of a system of nickel-based alloys in a heating element sheath. The patent look for the best balance between hot strength, corrosion resistance and cost for those systems. See the Google Patents heating element sheath record.
Same alloy name can still hide the wrong purchase if the drawing says plate but the supplier quotes a generic nickel alloy bar. At TiAlloy, the RFQ starts with form, standard, size, tolerance and record pack before price.
