applicationed: 

The Ti of 321 stainless steel pipe  as a stabilizing element exists, but it is also as a hot steel, in terms of high temperature is better than 316 l. 321 stainless steel pipe 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.

 

The 321 stainless steel pipe is a ni-cr-ti austenitic stainless steel, whose performance is very similar to that of 304, but with the addition of metal titanium, it has better resistance to grain and high temperature.Due to the addition of metal titanium, it effectively controls the formation of chromium carbide.

 

321 stainless steel pipe has excellent high temperature Stress Rupture performance and Creep Resistance. The mechanical properties of Creep Resistance are better than 304 stainless steel.Suitable for high temperature welding components.
