I-SUPER DUPLEX S32760 / F55 / 1.4501
INKCAZO
1.Ukubonelela ngamandla aphezulu kunezo zombini i-austenitic kunye ne-22% ye-Cr Duplex Stainless Steels UNS S32760 (F55) ifanelekile kwiintlobo ezahlukeneyo zezicelo kumashishini afana ne-Oil & Gas, i-CPI (i-Chemical Processing Industries), kunye neendawo zaseLwandle.
I-UNS S32760 (F55 / 1.4501) idweliswe kwi-NACE MR 01 75 ngenkonzo emuncu kwaye ifumene imvume ye-ASME yezicelo ze-Pressure Vessel.
amanqanaba amandla ngonyango olulula lobushushu kwiiMeko ze-RH 950 kunye ne-TH 1050. Amandla aphezulu aphezulu e-Condition CH 900 inika iingenelo ezininzi apho u-ductility olinganiselwe kunye nokusebenza kuvumelekile.Kwimeko yayo yonyango lobushushu, le ngxubevange ibonelela ngeempawu ezikhethekileyo zomatshini kumaqondo obushushu ukuya kuma-900 °F (482 °C).
