ASTM B168 UNS N06600 Forging Rings for Roller Hearths Radiant Tubes

Nickel Alloy Forging Ring Inconel 600 UNS N06600 Roller Hearths Radiant Tubes

Nickle Alloy Ring are the most common in forged metals. Through open die forging,the metal is formed into something that's shaped like a doughnubefore it's heated between 400 and 700'c. Next, it's placed on a mandrel or idler rol that increases the steel ring's diameters and reduces thethickness of its walls. You can find them in machinery and equipment, vehicles, pipes and valves, and other hardware. Almost all vehicles and otherheavy machinery make use of them because they are durable and easy to replace and look for.

 Alloy 600 (UNS N06600) is a nickel-chromium alloy designed for use fromcryogenic to elevated temperatures in the range of 2000F(1093 °C) qood oxidation resistance at higher temperatures, with good resistance in carburizing andchloride containing environments. The high nickel contentof the aloy enables it to retain considerable resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds.The nickel content gives it excellent
resistance to chloride-ion stress-corrosion cracking andalso provides excellent resistance to alkaline solutions. Its chromium content gives the alloy resistance to sulfurcompounds and various oxidizing environments. The chromium content of the alloy makes it superior to commercially pure nicke under oxidizing conditions.rstrong oxidizing solutions, like hot concentrated nitricacid,600 has poor resistance. Alloy 600 is relativelyunattacked by the majority of neutral and alkaline saltsolutions and is used in some caustic environments. 

Applications
Thermocouple sheaths / Ethylene dichloride (EDC) cracking tubes / Conversion of uranium dioxide to tetrafluoride in contact with hydrofluoric acid / Production of caustic alkalis particularly in the presence of sulfur compounds / Reactor vessels and heat exchanger tubing used in the production of vinyl chloride / Process equipment used in the production of chlorinated and fluorinated hydrocarbons / Furnace retort seals, fans, and fixtures/Roller hearths and radiant tubes, especially in carbonnitriding processes / Heat treating muffles and retorts / Vacuum furnace fixtures.Chlorination equipment to 1000°F Titanium dioxide plants,

Machining:
Nickel based alloys can be difficult tomachinine.However, it should be emphasized that thesealloys can be machined using conventional productionmethods at satisfactory rates. These alloys harden rapidlygenerate high heat during cutting, weld to the cuttingtool surface and offer high resistance to metal removabecause of their high shear strengths. The following arekey points which should be considered during machining operations: capacity/tools/positive cut/lubrication.
