I-SAE 304 Insimbi Engagqwali iyinsimbi evame kakhulu engenacala. Insimbi iqukethe zombili i-chromium (phakathi kuka-18% no-20%) kanye ne-nickel (phakathi kuka-8% kanye ne-10,5%) [1] izinsimbi njengezicini ezingezona zensimbi. Kuyinsimbi engelutho engagqwali. Akukancane ngogesi nakwesobunxele kunensimbi yekhabhoni. Kuyinto kazibuthe, kepha kazibuthe kakhulu kunensimbi. Inokumelana nokuqina okuphezulu kakhulu kunensimbi ejwayelekile futhi isetshenziswa kabanzi ngenxa yokukhululeka lapho kwakhiwa khona ngezimo ezahlukahlukene. [1]
I-ASTM A182 F304 Ama-Flanses ensimbi engenasici akhiqizwa ngokuya nge-ASME B16.5 150 #, 300 #, 900 #, 1500 #, 2500 #, 2500 #, 2500 #
Ngalesi sikhathi esiphezulu sokuncibilika, i-flange ingamelana namazinga okushisa aze afike ku-870 degrees Celsius. Kunezinhlobo ezahlukene ze-flanges ngokuya ngohlobo lobuso. Ama-flinges ensimbi engagqwali atholakala ngamalunga amafulethi, aphakanyisiwe futhi akhala.
Ibanga lensimbi elingagqwali, ukwakheka kwamakhemikhali kwama-flanges wensimbi engenasici akunikeza ithuba ngaphezulu kwamabanga ajwayelekile e-carbon. Yize bebiza ngaphezu kwe-alloys yangaphambilini, ukusebenza abakunikezayo kuthatha izinhlelo zokusebenza ezingeni elilandelayo.
Ezimbonini eziphatha i-nitric acid, ama-flange amapayipi wensimbi angama-304 angenacala I-304 amalangabi ensimbi engagqwali ahlala isikhathi eside futhi abiza kakhulu kunezinye izinhlobo ze-alloy. Ngenxa yezakhiwo ze-oxidizing zalesi sixazululo, kuzodala ukuhlukaniswa uma kusetshenziswa ekugxileni ngaphezulu kwama-55%.
