AISI 321 Stainless Steel Pipe
At elevated temperatures, pipes that are welded are prone to intergranular corrosion. Though there are multiple causes for this, the main cause of corrosion according to 321 Stainless Steel Pipe Suppliers is the precipitation of chromium carbides in the HAZ that occurs in the weld seam.

On the latitudinal weld seam, the free carbon atoms get attached to the free chromium atoms that are present on the surface of the steel. This reaction takes place at a considerably higher temperature range of 800°F to 1500°F. The deposition of chromium carbides weakens the weld seam by making it vulnerable, leading to the corrosion of Ss 321 Welded Pipe.
The newly formed titanium carbide has no effect whatsoever on the grade 321 Stainless Steel Seamless Pipe. Additionally, titanium carbide has a strengthening effect on the material, along with providing some form of corrosion resistance to the Seamless 321 Stainless Steel Tubing.
