Excellent high temperature stress breaking performance 321 Stainless Steel Square Pipe
321 stainless steel square pipe characteristics
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 different 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 pipeline.
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.
321 stainless steel has excellent high temperature stress breaking performance and high temperature creep resistance stress mechanical properties are better than 304 stainless steel
Heat treatment range
1.Quick cooling of solution 920~1150℃ :
2. Stabilization treatment can be carried out according to the requirements of the demander. The heat treatment temperature is 850~930℃, but it must be indicated in the contract;
3. The solution temperature should not exceed 1066℃. If it does, it must be stabilized to prevent chromium precipitation.
