Inconel 601 Industrial Terminology: Nickel-Chromium Alloy; Werkstoff Nr. 2.4851, UNS N06601, Pyromet 601, NiCrofer 601
Inconel 601 is suitable for applications requiring maximum high temperature thermal resistance and corrosion resistance up to 1100oC. Due to the presence of nickel, this alloy is highly resistant to oxidation up to 2200oF or 1250oC. It produces an extremely reliable oxide layer to prevent flaking under severe thermal cycling. High metallurgical stability and excellent creep rupture strength. It avoids SIGMA development and is suitable for use in thermal cycling and shock operations.
Superalloy 601 has good mechanical properties at high temperatures. Good strength can be achieved by cold solution or precipitation strengthening on the basis of the alloy. The alloy has good ductility even with long-term use. It is easy to shape, process and weld.
Inconel 601 Application
Industrial Furnace Components - Stills, Heat Exchangers, Petrochemical, Thermal Processing Industries, Aerospace and Land-Based Gas Turbines, Rocket Engine Nozzles, Chemical Processing, Nitric Acid Production, Radiant Tubes, Boilers, Turbocharger Rotors, ASME Section 8 Compliant Reliable materials are required for pressure vessels, exhaust systems, reactors producing nuclear steam and pollution control.
Excellent antioxidant alloy 601 is used in combustion equipment, such as solid waste incineration and superheated tube supports in power generation equipment.
In addition to becoming an essential material in aviation gas turbines, Inconel 601 also finds an important role in applications requiring high temperature strength and controlled oxidation. It has higher strength than standard grades and is therefore suitable for heavier refractories above 1150oC.
Inconel 601 Corrosion Resistance
Alloy 601 has strong oxidation resistance at high temperatures. It also prevents flaking up to 1260oC. The fixed oxide layer prevents peeling in strong media and avoids carburization and nitriding. The alloy is also moderately resistant to sulfur and vanadium oxides.
processing
Alloy 601 can be processed using conventional processing methods. It has higher strength than standard steel grades and hardens when machined, so heavy-duty machining tools are recommended. Standard coolant is suitable for use. Water-based coolants can be used in high-speed procedures, including turning and milling. Carbide equipment is used for regular cutting and turning. Discontinuous cuts must be made using high-speed steel tools to achieve finishing to tight tolerances. Use a tool with a positive rake angle. A constant feed rate must be used to prevent work hardening due to the drill bit resting on the metal. A strong system is important, for example a short pile drill bit is suitable. Heavy-duty and high-speed steel drill bits with heavy-duty webs are preferred.
forming
Alloy 601 can be easily formed by standard methods. It is stronger than ordinary steel. Use heavy-duty lubricants when cold forming. It is important to thoroughly remove all traces of lubricant after the part is formed, as embrittlement can occur at high temperatures if lubricant is left behind.
welding
Alloy 601 can be easily welded using conventional welding techniques. Clean weldable surfaces to remove any oil, paint or crayon stains. The recommended joining methods for this alloy are TIG welding, shielded metal arc welding, and gas metal arc welding. Electrodes should be stored in a dry place to avoid any interaction with moisture. Thorough removal of slag is critical before subsequent weld passes and after the final weld.
