To manufacture 321 stainless steel, type 304 stainless steel underwent minor processing changes. Titanium was added to the formulations, and the carbon content of the other formulation increased by a factor of five. Titanium is incorporated into the alloy to reduce the risk of carbide precipitation both during the welding process and in conditions where there is a wide temperature range. Please do not hesitate to contact us with questions regarding 321 stainless steel.
Despite the addition of titanium, 321 stainless steel has managed to keep many characteristics that make the 300 series of stainless steel unique. Among the many high-temperature applications that call for stainless steel 321, some of the most popular include heavy-duty automotive exhaust systems, firewalls, stack liners, and airplane components.
Carbide Precipitation is commonly brought up in conversations about stainless steel from the 300 series. The concept is easy, yet it depends on the fusing of metallic elements. When exposed to high temperatures, it is typical for metals to fuse, which results in the creation of a denser metal. This process will form chromium carbide, a thicker metal produced when stainless steel’s chrome and carbon atoms interact with one another.
Because it eliminates important properties, this fusion process should be avoided regarding stainless steel. Your stainless steel may become less resistant to corrosion if you deplete its chromium, for instance, by producing another metal. This can happen if you manufacture another metal. On the other hand, even if the stainless steel is architecturally more susceptible to corrosion in certain areas, its integrity will still deteriorate due to structural pathways leading to forming these two metals. This is because these structural pathways lead to the formation of both of these metals.
The presence of titanium in stainless steel 321 prevents this from happening, which enables it to withstand higher temperatures for more extended periods than other stainless steel in the 300 families. As a result, the metal can be machined and shaped into appropriate applications or much less complicated shapes.
