The Ferrite to Austenite Transformation in Stainless Steels

Many wrought austenitic stainless steels exhibit a duplex austenitic-ferritic structure at room temperature after so­ lidification. The ferrite phase within the austenitic matrix is known to play a ben­ eficial role in the prevention of hot crack­ ing in both as-cast and as-welded struc­ tures.

How to weld Duplex Stainless Steel - Rolled Alloys, Inc.

Most duplex stainless steels have an over alloyed filler. For example, 2205 uses 2209 and ZERON 100 uses ZERON 100X. These filler metals are nearly identical in chemistry to the base metal, except for an extra 2% nickel. The increased nickel content aides in forming the 50/50 mix of austenite and ferrite …

Duplex stainless steel - imoafo

Duplex stainless steel. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure. As the material cools to room temperature, about half of the ferritic grains transform to austenitic grains (“islands”). The result is a microstructure of roughly 50% austenite and 50% ferrite.

Ferrite Content in Austenitic Stainless Steels - Rolled Alloys

Ferrite Content in Austenitic Stainless Steels. Ferrite reduces the tendency for the steel to solidification crack during cooling. It is not uncommon for 304 castings (CF8) to contain 8 -20% ferrite. The cast ingot composition of wrought 304 stainless is also balanced to have 1 -6% ferrite since this reduces the chance of cracking during forging or hot working.
