- 321 stainless steel is a Ni-Cr-Ti type of austenitic stainless steel. Its performance is very similar to 304, but the addition of the metal titanium gives it better intergranular corrosion resistance and high-temperature strength. The addition of titanium effectively controls the formation of chromium carbide.

321 is also called or known as UNS S32100. It is a non-magnetic and stabilized austenitic alloyor SS. Other identifiable names of 321 SS include: 1. AMS5510 2. AMS5645
It is non-magnetic.321 SS provides you with the best resistance to stress corrosion cracking.Great weldability due to its intergranular corrosion resisting attributes.Has high tensile and yield strength levels.Requires cold working to achieved some level of magnetism.Machining isn’t easy.When evaluating 321 SS properties, you should consider chemical, physical and mechanical attributes.
321 SS is equivalent to 304 SS. It is considered equivalent to 304 due to the similarities in their makeup elements or chemical composition. 321 SS has titanium elements while 304 doesn’t.
Corrosion resisting
321 SStakes the lead where corrosion resistance is concerned when compared to 316. Titanium in 321 gives its surface a protective oxide film. So, when exposed to water or even other chloride or sulfuric acid filled compounds, it stands tall.
Crevice and Pitting Corrosion
316 has better crevice and pitting corrosion than 321.
Inter-granular Corrosion
321 has the best inter-granular corrosion compared to 316 due to its high carbon content.
When buying this stainless steel grade, you may encounter other names such as: 1. UNSS32100 2. Nr.1.4541 3. AWS 133
Cold bending
321 cold bending is very simple. Mild magnetic features should be expected after cold working process.
Hot bending
Hot bends needs to be done at a minimum of 950°C and a maximum of 1100°C. Annealing must always come next after this procedure to restore higher corrosion resistance.
Forging
Forging shouldn’t be done below 900°C. Also, forgings completed need to be air cooled. Annealing forgings will increase the level of corrosion resistance in 321 SS.
You will find 321 SS in different forms such as flats, square, coil, foil, round bar, sheets, hex bar, and more.
