Metallographic arrangement for austenitic stainless steel 321, 321 stainless steel of Ti as a secure element exists, but it is hot steel at the same time, in 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 outstanding resistance to abrasion function, used to make the fabrics of wear resistant acid containers and equipment, transport pipeline.
Stainless steel is Ni - 321
Ti type austenitic stainless steel, its function and 304 are very similar, but because joined the metal titanium, make its have the better grain boundary corrosion resistance and high temperature strength.
Because the increase of titanium, making it useful to manipulate the composition of the chromium carbide.
