Faahfaahinta Alaabta
2507 waa bir bir ah oo super duplex ah oo leh waxyaabo ka kooban alloy sare, sidaas darteed waxay ka dhigaysaa mid ka sareysa 2205 iska caabin daxalka iyo xoogga. Waxay leedahay iska caabin heer sare ah oo ay u leedahay direyska, goynta, daxalka dillaaca iyo dildilaaca daxalka chloride. Sulfuric acid ku milmay oo ay ku wasakhoobeen ions chloride, 2507 waxay leedahay iska caabbinta daxalka ka wanaagsan 904L, taas oo si gaar ah loogu talagalay inay iska caabiso asiidhka sulfuric saafi ah. Sababtoo ah kaarboonka hooseeya ee 2507 wuxuu si weyn hoos ugu dhigayaa khatarta roobabka karbidhida ee xuduudaha hadhuudhka inta lagu jiro daweynta kulaylka, waxay aad ugu adkaysataa daxalka intergranular-la xidhiidha carbide. 2507 kuma habboona Codsiyada u baahan soo-gaadhista dheer ee heerkulka ka sarreeya 300 ℃ sababtoo ah khatarta sii kordheysa ee hoos u dhigista adkaanta. Awoodeeda wax-soo-saarku waxay ku saabsan tahay labanlaab ka badan biraha austenitic-ka caadiga ah.
S32507 Duplex walxo bir ah oo ay bixiso kooxda warshadaha Beall ayaa ah kuwa tayo sare leh.
Bar, tuubo, xaashi iyo saxan ayaa la bixin karaa.
