312 Stainless Steel Welded Tubes Erw Stainless Steel Pipe
321 stainless steel of Ti as a stabilizing element exists, but it
is also a hot steel, in terms of high temperature is better than
316 l. 321 stainless steel in different concentration and
temperature of organic acid and inorganic acid, especially in
oxidizing medium has good abrasion resistance, used in the
manufacture of the lining of wear resistant acid containers and
equipment and pipelines.
321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its
performance is very similar to 304, but because of the addition of
titanium metal, so that it has better grain boundary corrosion
resistance and high temperature strength. The formation of chromium
carbide is effectively controlled by adding titanium metal.
