S32750 Qalabka Agabka
2507 waa bir bir ah oo super duplex ah oo leh caabbinta daxalka iyo xoogga ka fiican 2205. Waxay isku daraysaa sifooyinka ugu faa'iidada badan ee birta ferritic iyo austenitic badan iyo, sababtoo ah maadada chromium iyo molybdenum sare, waxay leedahay iska caabin heer sare ah oo lebis ah, godad iyo daxalka dillaaca.Qaab-dhismeedka laba-waji wuxuu hubinayaa in birta ay leedahay iska caabin sare oo dillaaca daxalka walaaca iyo xoogga farsamada sare.
Maadada sare ee chromium iyo molybdenum waxa ay ka dhigtaa in ay iska caabin xoogan u yeelato daxalka guud ee acids organic sida formic acid, acetic acid, iwm.Marka la barbar dhigo 904L, kaas oo si gaar ah loogu talagalay inuu iska caabiyo asiidh sulfuric saafi ah, 2507 waxay leedahay iska caabin adag oo daxalka u ah sulfuric acid oo lagu qaso ion koloride.
Darajada 316L looma isticmaali karo deegaanka hydrochloric acid, waxaa laga yaabaa inay ku xiran tahay daxalka deegaanka ama daxalka guud, halka 2507 loo isticmaali karo jawiga hydrochloric acid ee la qasi karo, oo leh awood xoog leh oo ka hortag ah iyo anti-crevice awood.Maaddada hoose ee kaarboonka ee 2507 waxay si weyn u yaraynaysaa khatarta roobabka carbide ee intergranular inta lagu jiro daaweynta kulaylka, sidaas darteed, waxay aad ugu adkaysataa daxalka intergranular-ka ee carbide.
2507 waxay leedahay awood cadaadis sare leh, xoog saameyn leh iyo isugeynta fidinta kulaylka hooseeya iyo kuleylka kuleylka sare, sifooyinkani waxay ku habboon yihiin qaybo badan oo dhismo ah iyo qaybo farsamo.
2507 waa in aan la gelin deegaan heerkul ka sarreeya 300 ℃ muddo dheer, taas oo wiiqi karta adkaanteeda.
Iska caabinta Daxalka ee Walxaha S32750
1. Iska caabin daxalka
Maaddada sare ee chromium iyo molybdenum-ka ee SAF 2507 ayaa ka dhigaysa mid adkaysi u leh daxalka badan ee asiidhka organic sida formic acid iyo acetic acid.SAF 2507 alloy waxa kale oo ay iska caabin adag u leedahay asiidhyada inorganic, gaar ahaan kuwa ay ku jiraan chlorides.iska caabin daxalka.
Marka la barbar dhigo 904L, SAF2507 waxay leedahay iska caabin adag oo daxalka u leh sulfuric acid oo la qasi karo oo lagu qasay ion chloride.904L waa daawaha gobolka austenitic, si gaar ah loogu talagalay inay iska caabiso daxalka sulfuric acid saafi ah.
Darajada 316L looma isticmaali karo deegaanka hydrochloric acid, waxaa laga yaabaa in ay hoos timaado daxalka deegaanka ama daxalka guud.SAF2507 waxaa loo isticmaali karaa bey'ad hydrochloric acid oo la milo ah, oo leh awood adag oo ka hortag ah iyo awood dildilaaca.
2. Daxalka intergranular
Maaddooyinka hoose ee kaarboon ee SAF 2507 waxay si weyn u yaraynaysaa khatarta roobabka carbide intergranular inta lagu jiro daaweynta kulaylka, sidaas darteed, daawayntani waxay aad ugu adkaysanaysaa daxalka intergranular-la xidhiidha carbide.
3. Cadaadiska daxalka oo dillaaca
Qaab-dhismeedka laba-laabka ah ee SAF 2507 wuxuu ka dhigayaa mid aad ugu adkaysata dillaaca daxalka.Sababtoo ah maadada aluminiumka sare, caabbinta daxalka iyo xoogga SAF 2507 ayaa ka fiican 2205.
Dildilaaca dhismaha, iwm., taas oo ka dhigaysa birta aan-daxalka ahayn mid aad ugu nugul daxalka deegaanka chloride.SAF 2507 waxay leedahay awood xoog leh oo ay iskaga caabiso daxalka dillaaca.Qalooca isocorrosion ee SAF 2507 ee sulfuric acid ka kooban 2000ppm chloride ion 0.1 mm/sanad;qalooca isocorrosion ee hydrochloric acid 0.1 mm / sanad.
S32205 Goobaha Codsiga Qalabka
2507 birta aan lahayn waxaa loo isticmaalaa warshadaha saliidda iyo gaaska;meelaha saliida Shipotian ee xeebaha (tuubooyinka kulaylka, daaweynta biyaha iyo nidaamyada biyaha, nidaamyada ilaalinta dabka, hababka buufinta biyaha, nidaamyada xasilinta biyaha; qalabka petrochemical; desalination (desalination) qalabka (iyo qalabka tuubooyinka cadaadiska sare, tuubooyinka biyaha badda); iyo qaybaha qaab dhismeedka u baahan labadaba xoog sare iyo iska caabin daxalka sare leh, gubashada (dharka) qalabka gaaska sifaynta.
Dhuumaha warshadaha kiimikada, weelasha, kulaylka beddelashada, dhuumaha biyaha badda ee dhirta nadiifinta, saliida iyo qalabka warshadaha gaaska, warshad korontada nidaamka desulfurization gaaska flue, qalabka dhaqidda, munaaradaha nuugista, booyadaha dareere kiimikaad.
