ASTM A213 TP321 Bright Annealed Seamless Tube Rau Kub Exchanger

​​Vim li cas 321 stainless hlau feem ntau siv nyob rau hauv siab - qhov kub thiab txias?​​

321 stainless hlau yog ua los ntawm austenitic 18/8 steel (304 steel) thiab ruaj khov los ntawm kev ntxiv titanium alloy. Nws yog qhov zoo dua vim tias nws tiv thaiv intergranular corrosion thaum rhuab hauv carbide nag lossis daus kub ntau (425-850 degree). Rau cov ntawv thov nrog kev ua haujlwm kub txog li 900 degree, 321 stainless hlau yog cov hlau xaiv.

 

​Dab tsi yogASTM A213 TP321 Kub Exchanger Tube?​​

ASTM A213 TP321 yog ib qho austenitic stainless hlau siv los tsim cov raj seamless, haum rau kev siv xws li cov khoom siv hluav taws xob, superheaters, thiab boilers. Nws cov yam ntxwv tseem ceeb suav nrog titanium alloy stabilization, uas tiv thaiv kev tsim ntawm chromium carbides thiab txhim kho nws cov kev tiv thaiv rau intergranular corrosion ntawm qhov kub siab (800-1500℃F lossis 427-816 degree). Cov raj no tau ua tiav nrog cov txheej txheem "ci annealing" kom ua tiav qhov chaw du, siab ductility, thiab kev ntxhov siab thaum tsim khoom.
