Tuubo aan kala go 'lahayn oo S32750 ah
Hordhac Badeecada
Super Duplex oo aan lahayn bir sida S32750, waa qaab-dhismeed isku dhafan oo ah austenite iyo ferrite (50/50) kaas oo kor u qaaday xooggiisa marka loo eego heerarka birta ferritic iyo austenitic. Farqiga ugu weyn ayaa ah in Super Duplex uu leeyahay molybdenum iyo chromium sare oo siiya walxaha mid weyn Chromium sare sidoo kale wuxuu kor u qaadaa sameynta marxaladaha birta ee waxyeelada leh, kuwaas oo u nugul 475°C embrittlement sababtoo ah roobabka marxaladda α-hodanka ku ah chromium, iyo embrittle by sigma, chi iyo marxaladaha kale heerkulka sare.
Daawaha 2507 (S32750) sidoo kale wuxuu leeyahay maaddo nitrogen oo sareysa, taas oo aan kaliya kor u qaadin sameynta austenite oo kordhisa xoogga, laakiin sidoo kale dib u dhigta sameynta marxaladaha birta ku filan si loo oggolaado farsamaynta iyo soo saarista heerka laba-laablaha ah.
Darajada waxaa lagu gartaa iska caabin aad u wanaagsan oo daxalka koloriin ah, oo ay weheliso xoog farsamo oo aad u sarreeya. Waxay si gaar ah ugu habboon tahay in loo isticmaalo jawiyo dagaal badan sida biyaha badda ee diirran ee koloriin lagu daray iyo warbaahinta ay ku jirto koloriin aashito leh.
Astaamaha Daawaha 2507 (S32750) waa sida soo socota:
● Iska caabin aad u fiican oo ku wajahan dillaaca daxalka (SCC) ee deegaannada koloriin-ku-saleysan
● Iska caabin aad u fiican oo ku wajahan daxalka iyo daloolka
● Iska caabin sare oo ku wajahan daxalka guud
● Awood farsamo oo aad u sareysa
● Sifooyinka jireed ee bixiya faa'iidooyinka naqshadeynta
● Iska caabin sare oo ka dhan ah daxalka nabaad guurka iyo daxalka
● Alxan wanaagsan
S32750 waxaa loogu talagalay codsiyada adag ee u baahan xoog gaar ah iyo iska caabin daxalka, kuwaas oo laga helohabka kiimikada, qalabka batroolka kiimikada, iyo biyaha badda. Waxaa si weyn loogu isticmaalaa sahaminta/soo-saarka saliidda iyo gaaska badda iyo beddelayaasha kulaylka ee farsamaynta batroolka/kiimikada. Darajadani waxay sidoo kale ku habboon tahay codsiyada haydarooliga iyo qalabka ee deegaannada badda ee kulaylaha.
