  304 corrosion resistance of stainless steel tee: average erosion: 304 stainless steel tee, because of chromium content (22%), molybdenum (3%) and nitrogen content (0.18%), 2205 corrosion resistance in most environment is better than 316L and 317L. 316 stainless steel tee local corrosion resistance: 304 stainless steel in the content of chromium, molybdenum and nitrogen in the oxidation and acid solution, the point of erosion and gap erosion has a strong ability to resist. Stress corrosion resistance: the duplex microstructure of 304 stainless steel tee helps to improve the anti stress cracking ability of stainless steel.

  In the presence of certain temperatures, stresses, oxygen and chlorides, the austenitic stainless steel will have a chloride stress invasion of 316 stainless steel tee because these prerequisites are not easily controlled, so the use of 304L, 316L and 317L is limited in this respect. Corrosion resistance fatigue: high strength and corrosion resistance of 304 stainless steel make it highly resistant to corrosion and fatigue. Processing equipment is vulnerable to eroded environment and loading cycles. 2205 of the characteristics are very suitable for such applications.

  The atmosphere is annealed.Stainless steel tees are generally used as pure hydrogen as the annealing atmosphere, and the purity of the atmosphere is better than 99.99%. If the other department in the atmosphere is inert gas, the purity can be a little lower, but it can not contain too much oxygen and water vapor. Whether the annealing temperature can reach the delimited temperature. 316 the heat treatment of stainless steel tee is usually treated by solid solution heat treatment, which is commonly called "annealing". You can also observe the holes in the annealing furnace. The stainless steel tee in the annealed area should be incandescent, but no softening and drooping will occur.
