1. Inconel 601 Overview:
Inconel 601 is a nickel-chromium alloy used for applications that
require resistance to corrosion and heat. This nickel alloy stands
out due to its resistance to high temperature oxidation, remaining
highly resistant to oxidation through 2200° F. Alloy 601 develops a
tightly adherent oxide scale which resists spalling even under
conditions of severe thermal cycling. This nickel alloy has good
high temperature strength, and retains its ductility after long
service exposure. It has good resistance to aqueous corrosion, high
mechanical strength, and is readily formed, machined and welded.
Inconel 601’s properties make it a material of broad utility in
fields like thermal processing, chemical processing, pollution
control, aerospace, and power generation. However, alloy 601 is not
suggested for use in strongly reducing, sulfur bearing
environments.

4.Fabrication and Heat Treatment for Inconel 601:
Machinability
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.
Forming
Inconel 601™ is formed using all conventional techniques.
Welding
Inconel 601™ is welded using gas-tungsten arc welding, gas
metal-arc welding, shielded metal-arc welding, and submerged-arc
welding methods.
Heat Treatment
Inconel 601™ does not respond to heat treatment.
Forging
Inconel 601™ is forged at 1038 to 1233°C (1900 to 2250°F)
Hot Working
Inconel 601™ is hot worked at 872 to 1233°C (1600 to 2250°F)
Cold Working
Inconel 601™ can be cold formed using standard tooling.
Annealing
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.
Hardening
Inconel 601™ can be hardened only by cold working.
