 Fabrication and Heat TreatmentCold WorkingStandard cooling methods are used for cold forming Udimet 520™. Minimization of galling is possible with the usage of heavy duty lubricants and soft die materials though the die life is limited. Tooling is recommended in the cold working process to allow liberal radii and clearances. WeldingWelding processes recommended for Udimet 520™ include gas-tungsten arc welding, gas metal-arc welding and shielded metal-arc welding. This alloy can be welded by the commonly used welding procedures, and the welding surfaces should be free from paint, crayon markings or oil. ForgingUdimet 520™ is capable of being forged as it is ductile. FormingConventional methods can be used to form Udimet 520™ with ease as it has good ductility. To obtain good forming results, a powerful equipment is used along with heavy- prevent embrittlement of this alloy at high temperatures. MachinabilityUdimet 520™ can be machined by conventional machining methods. and tThis alloy contains higher strength, gumminess and work-hardening qualities. Usage of water-based coolants is preferred for milling, turning or grinding. Usage of heavy lubricants is preferred for boring, drilling, broaching or tapping operations. Work-hardening of the alloy before the cutting process and chatter can be minimized by tooling and a heavy duty machining equipment. AgingUdimet 520™ is treated at three different temperatures to be air-hardened.
Heat TreatmentUdimet 520™ can be hardened when heat treated.
Industrial & Aerospace ApplicationsWith its outstanding high-temperature resistance, high strength and excellent processability, Udimet 520 superalloy is widely used in core high-temperature components of aerospace, energy and high-end industrial equipment:
