I-SUPER DUPLEX S32760 / F55 / 1.4501
DESCRIPTION
1.Inikeza amandla aphakeme kunawo womabili ama-austenitic kanye nama-22% e-Cr Duplex Stainless Steels UNS S32760 (F55) ifaneleka ezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezifana ne-Oil & Gas, CPI(Chemical Processing Industries), kanye nezindawo zasolwandle.
I-UNS S32760 (F55 / 1.4501) isohlwini lwe-NACE MR 01 75 ngesevisi emuncu futhi ithole Ukugunyazwa kwe-ASME kwezicelo zomkhumbi Wokucindezela.
amazinga wamandla ngokwelashwa okulula kokushisa kuZimo RH 950 kanye ne-TH 1050. Amandla aphezulu kakhulu e-Condition CH 900 anikeza izinzuzo eziningi lapho ukuduka okulinganiselwe nokusebenza kuvunyelwe. Esimeni sayo sokwelashwa ngokushisa, le ngxubevange ihlinzeka ngezakhiwo ezihlukile zomshini emazingeni okushisa afika ku-900 °F (482 °C).
