Super alloys or high performance alloys are strengthened by performing solid-solution hardening, work hardening, and precipitation hardening. They have good creep and oxidation resistance, and consist of elements in a variety of combinations to achieve the desired result. They can be used at very high temperatures and mechanical stress, and also where high surface stability is required.

Fabrication and Heat Treatment
Inconel 601™ can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-based coolants. Heavy lubricants are used for tapping, drilling, boring, or broaching.
Inconel 601™ is formed using all conventional techniques.
Inconel 601™ is welded using gas-tungsten arc welding, gas metal-arc welding, shielded metal-arc welding, and submerged-arc welding methods.
Inconel 601™ does not respond to heat treatment.
Inconel 601™ is forged at 1038 to 1233°C (1900 to 2250°F)
Inconel 601™ is hot worked at 872 to 1233°C (1600 to 2250°F)
Inconel 601™ can be cold formed using standard tooling.
Inconel 601™ is annealed at 1149°C (2100°F). It is then cooled at temperatures ranging from 538 to 760°C (1000 to 1400°F) in order to prevent thermal cracking.
Inconel 601™ can be hardened only by cold working.
Inconel 601™ is used in heat treat furnace fixtures and components such as muffles, annealing tubes, and flame shields. It can also be used in chemical process equipments which include process heaters, combustor components, and condenser tubes.
