Austenitic Stainless Steels

These are the most commonly used corrosion resistant alloys and typically what is thought of when the generic term “stainless steel” is used. These alloys provide good toughness and corrosion resistance even at cryogenic temperatures.

Alloy Properties
Representative AlloysCF8, CF8M, CN7M
ApplicationsMost widely used corrosion resistant Alloys; useful at temperatures from cryogenic to 1000 F (500 C), depending on the grade
LimitationsSpecial grades available for applications requiring higher strength, low magnetic permeability, etc.
Typical UsesChemical processing, marine, power plant, pulp and paper, fertilizer, food and dairy
WeldabilityGenerally very good; fully austenitic grades may require special procedures
Corrosion ResistanceThough some grades are used as-cast, heat treatment maximizes corrosion resistance
