Ingxubevange 625 / UNS N06625 / W.NR. 2.4856

Incazelo

I-alloy 625 iyingxubevange ye-nickel-chromium-molybdenum esetshenziselwa amandla ayo aphezulu, ukuqina okuphezulu kanye nokumelana nokugqwala okuhle kakhulu. Amandla e-alloy 625 asuselwa kumphumela wokuqina we-molybdenum ne-niobium ku-matrix yayo ye-nickel-chromium. Nakuba ingxubevange yenzelwe amandla okushisa aphezulu, ukwakheka kwayo okunengxubevange ephezulu nakho kunikeza izinga elibalulekile lokumelana nokugqwala okujwayelekile.

Izimboni kanye nezicelo

I-alloy 625 isetshenziswa ezimbonini ezahlukahlukene, ezihlanganisa ezezimoto, zasolwandle, i-aerospace, uwoyela negesi, ukucubungula amakhemikhali kanye nezenuzi. Izinhlelo zokusebenza ezijwayelekile zokusetshenziswa zifaka izishintshi zokushisa, ama-bellows, amajoyinti okunweba, amasistimu e-exhaust, izixhumi, izixhumi ezisheshayo nezinye izinhlelo zokusebenza eziningi ezidinga amandla nokumelana nezindawo ezilimazayo.

Ukumelana Nokugqwala

I-alloy 625 inokumelana okuhle ne-oxidation kanye nokukala emazingeni okushisa aphezulu. Ku-1800°F, ukumelana nokukala kuba yinto ebalulekile enkonzweni. Iphakeme kunamanye ama-alloys amaningi okushisa aphezulu ngaphansi kwezimo zokushisisa ngama-cyclic kanye nezimo zokupholisa. Inhlanganisela yezinto ezihlanganisiwe ku-alloy 625 iyenza ikwazi ukumelana nezinhlobonhlobo zezindawo ezigqwalile. Cishe akukho ukuhlasela ezindaweni ezithambile, njengamanzi amasha namanzi olwandle, izindawo ezingathathi hlangothi ze-pH, kanye nemidiya ye-alkaline. Okuqukethwe kwe-chromium yale alloy kubangela ukumelana okuphakeme nezindawo ezine-oxidizing. Okuqukethwe okuphezulu kwe-molybdenum kwenza i-alloy 625 imelane kakhulu nokugqwala nokugqwala kwemifantu.

Ukwenziwa kanye Nokwelashwa Kokushisa

I-alloy 625 ingakhiwa kusetshenziswa izinqubo ezahlukahlukene zokusebenza ezibandayo nezishisayo. I-alloy 625 imelana nokuguquguquka emazingeni okushisa okushisa okusebenza, ngakho-ke imithwalo ephezulu iyadingeka ukwenza izinto. Ukwakhiwa okushisayo kufanele kwenziwe ngaphakathi kwebanga lokushisa elingu-1700° ukuya ku-2150°F. Ngesikhathi sokusebenza okubandayo, umsebenzi wezinto ezibonakalayo uba lukhuni ngokushesha kunezinsimbi ezingenasici ze-austenitic zendabuko. I-alloy 625 inezinto ezintathu zokwelapha ukushisa: 1) isixazululo se-annealing ku-2000/2200°F kanye nokucisha komoya noma ngokushesha, 2) ukudonsa okungu-1600/1900°F nokucisha komoya noma ngokushesha futhi 3) ukukhulula ingcindezi ku-1100/1500°F nokucisha komoya. . Isixazululo esihlanganisiwe (ibanga lesi-2) sivame ukusetshenziselwa izinhlelo zokusebenza ezingaphezu kuka-1500°F lapho ukumelana nokukhasa kubalulekile. I-Soft-annealed material (ibanga loku-1) ijwayele ukusetshenziselwa amazinga okushisa aphansi futhi inenhlanganisela efanele yezindawo eziqinile neziqhekeka.
