Unlike 304, Grade 321 is stabilized with titanium, which prevents chromium carbide precipitation at the grain boundaries during high-heat exposure, thereby avoiding intergranular corrosion.
It is primarily used in the petrochemical industry, aerospace, heat treatment furnaces, and high-temperature food/pharmaceutical processing.
Yes, AISI 321 offers excellent weldability using various methods, and in most industrial applications, preheating the material is not required.
The recommended service temperature range is generally between 600°C and 900°C, depending on the surrounding environment and load.
In its untreated state, it exhibits weak magnetic behavior, but it becomes non-magnetic after appropriate heat treatment.
While highly resistant, environments containing high concentrations of sulfur compounds may reduce the corrosion resistance of AISI 321.
