Ibisobanuro

Alloy 625 ni nikel-chromium-molybdenum alloy ikoreshwa kubwimbaraga zayo nyinshi, gukomera kwinshi no kurwanya ruswa. Imbaraga za alloy 625 zikomoka ku ngaruka zikomeye za molybdenum na niobium kuri materique ya nikel-chromium. Nubwo ibinyomoro byakozwe kugirango ubushyuhe bwo hejuru, ibivanze cyane kandi bitanga urwego runini rwo kurwanya ruswa.

Inganda na Porogaramu

Alloy 625 ikoreshwa mu nganda zitandukanye, zirimo imodoka, inyanja, ikirere, peteroli na gaze, gutunganya imiti na kirimbuzi. Ubusanzwe imikoreshereze yanyuma ikoreshwa harimo guhinduranya ubushyuhe, inzogera, guhuza kwaguka, sisitemu yo kuzimya, kwizirika, guhuza byihuse nibindi bikoresho byinshi bisaba imbaraga no kurwanya ibidukikije byangiza.

Kurwanya Ruswa

Alloy 625 ifite imbaraga zo kurwanya okiside no gupima ubushyuhe bwinshi. Kuri 1800 ° F, kurwanya ibipimo biba ikintu gikomeye muri serivisi. Iruta izindi nyinshi zubushyuhe bwo hejuru murwego rwo gushyushya no gukonjesha. Ihuriro ryibintu bivanze muri alloy 625 ituma ishobora guhangana nubwoko butandukanye bwibidukikije byangirika. Nta gitero kiboneka ahantu horoheje, nk'amazi meza n'amazi yo mu nyanja, ibidukikije bya pH bidafite aho bibogamiye, hamwe n'itangazamakuru rya alkaline. Chromium yibiri muri aya mavuta bivamo imbaraga zo kurwanya ibidukikije. Ibirungo byinshi bya molybdenum bituma alloy 625 irwanya cyane gutobora no kwangirika.

Guhimba no kuvura ubushyuhe

Alloy 625 irashobora gushirwaho ukoresheje inzira zitandukanye zikonje kandi zishyushye. Alloy 625 irwanya ihinduka ryubushyuhe bwakazi, kubwibyo umutwaro uremereye urasabwa gukora ibikoresho. Gukora bishyushye bigomba gukorwa mubushyuhe bwa 1700 ° kugeza 2150 ° F. Mugihe gikonje gikora, imirimo yibikoresho irakomera byihuse kuruta ibyuma bya austenitis gakondo. Alloy 625 ifite uburyo butatu bwo kuvura ubushyuhe: 1) gukemura ikibazo kuri 2000/2200 ° F no kuzimya ikirere cyangwa byihuse, 2) guhuza 1600/1900 ° F no kuzimya ikirere cyangwa vuba na 3) guhagarika umutima kuri 1100/1500 ° F no kuzimya ikirere. . Igisubizo cyometseho (icyiciro cya 2) gikunze gukoreshwa mubisabwa hejuru ya 1500 ° F aho kurwanya kunyerera ari ngombwa. Ibikoresho byoroheje (icyiciro cya 1) bikoreshwa cyane mubushyuhe bwo hasi kandi bifite uburyo bwiza bwo guhuza ibintu hamwe no guturika.
