3. Hot and Cold Forming
Alloy 617 has good hot formability, but it requires relatively high forces because of its inherent strength at elevated temperatures. In general, the hot-forming characteristics of alloy 617 are similar to those of INCONEL alloy 625. The temperature range for heavy forming or forging is 1850 to 2200°F (1010 to 1205°C). Light working can be done at temperatures down to 1700°F (925°C). INCONEL alloy 617 is readily cold formed by conventional procedures although its work-hardening rate. For best results, the alloy should be cold formed in the fine-grain condition, and frequent intermediate anneals should be used. Annealing for cold forming should be done at 1900°F (1040°C).
4. Heat Treatment
INCONEL alloy 617 is normally used in the solutionannealed condition. That condition provides a coarse grain structure for the best creep-rupture strength. It also provides the best bend ductility at room temperature. Solution annealing is performed at a temperature of 2150°F (1175°C) for a time commensurate with section size. Cooling should be by water quenching or rapid air cooling.
Cutting tools should be sharp and have positive rake angles to minimize work hardening of the material. Cutting feed and depth of cut must be sufficient to prevent burnishing of the workpiece surface.
INCONEL alloy 617 has excellent weldability. INCONEL Filler Metal 617 is used for gas-tungsten-arc and gas-metalarc welding while INCONEL Welding Electrode 117 is used for shielded metal-arc welding. The composition of the filler metal matches that of the base metal, and deposited weld metal is comparable to the wrought alloy in strength and corrosion resistance.
Alloy 617 has excellent resistance to oxidation and carburization at high temperatures. It also resists a wide range of corrosive aqueous environments. Alloy 617 has high strength and maintains much of its strength at elevated temperatures.
