Kuvanga ibyuma 20

Alloy 20 (UNS N08020) ni austenitis, nikel-fer-chromium ishingiye kuri super alloy hiyongereyeho Umuringa na Molybdenum bitanga imbaraga zo kurwanya ibidukikije bibi, gutobora, no kwangirika. Irahagaritswe kandi na Columbium kugirango igabanye imvura ya karbide mugihe cyo gusudira. Alloy 20 isa nkaho iguye hagati yicyiciro cyose kitagira umwanda na nikel kuko kirimo ibiranga byombi. Yashizweho kugirango irwanye cyane aside yibasiwe kandi yerekana ko irwanya imbaraga za ruswa zangirika mu guteka 20% kugeza kuri 40% ya acide sulfurike, kandi ifite kandi ruswa muri rusange irwanya ruswa ya acide sulfurike ndetse no guturika kwa chloride. Alloy 20 ifite imiterere yubukorikori haba mubidukikije ndetse no hejuru yubushyuhe, kugeza kuri 930 ° F (500 ° C) kandi bihimbwa byoroshye nibikorwa bisanzwe byinganda.

Ibiranga

• Kwangirika kwinshi, gutobora no guhangana na crevice
• Harimo Niobium yo gutuza irwanya ubukangurambaga no kuvamo kwangirika
• Ibikoresho byiza byubukanishi no guhimba
• Imvura nkeya ya karbide mugihe cyo gusudira

Porogaramu
Bitewe nuko irwanya ruswa, Alloy 20 ikoreshwa mugutunganya imiti, umusaruro wibiribwa, imiti, kubyara amashanyarazi no gukoresha plastike. Valves, pompe na sisitemu ya progaramu ni bimwe mubice bizwi cyane aho Alloy 20 ikoreshwa.
