S32750 Ibyuma Bitagira Umugozi Bidafite Ingufu

Super Duplex stainless nka S32750, ni imiterere ivanze ya austenite na ferrite (50/50) byazamuye imbaraga kurusha ferritic na austenitic steel grades. Itandukaniro rikomeye ni uko Super Duplex ifite molybdenum na chromium nyinshi, ibyo bigatuma ibikoresho birushaho kuba byinshi. Chromium nyinshi kandi itera imbere kuremwa kwa intermetallic phases mbi, zishobora kwangirika ku bushyuhe bwa 475°C bitewe n'imvura ya phase ya α' ikunzwe na chromium, no kwangirika kubera sigma, chi n'izindi phases ku bushyuhe bwinshi.

Alloy 2507 (S32750) ifite kandi azote nyinshi, idatuma habaho ikorwa rya austenite gusa kandi ikongera imbaraga, ahubwo inatinza ikorwa ry’ibice by’ubutare hagati y’icyuma kugira ngo yemererwe gutunganya no gukora ubwoko bwa duplex.

Ingano irangwa no kurwanya ingese ya chloride neza cyane, hamwe n'imbaraga nyinshi za mekanike. Ikwiriye cyane gukoreshwa ahantu hashyushye nko mu mazi ashyushye ya chlorine n'ibice birimo aside chloride.

Ibiranga Alloy 2507 (S32750) ni ibi bikurikira:

● Ubudahangarwa bwiza bwo kurwanya stress corrosion crashing (SCC) mu bidukikije bifite chloride
● Ubudahangarwa bwiza bwo kwangirika kw'ibinogo n'imirongo
● Ubudahangarwa bukomeye ku kwangirika muri rusange
● Ingufu nyinshi cyane za mekanike
● Imiterere ifatika itanga ibyiza byo gushushanya
● Ubudahangarwa bukomeye ku ishwagara no kunanirwa kwangirika kw'isuri
● Uburyo bwiza bwo gusudira

S32750 yagenewe gukoreshwa mu buryo bukomeye kandi busaba imbaraga zidasanzwe no kurwanya ingese, nk'uko biboneka muriuburyo bwo gukoresha imiti, ibikoresho bya peteroli, n'amazi yo mu nyanja. Ikoreshwa cyane mu gushakisha/gukora peteroli na gaze mu nyanja ndetse no mu byuma bihindura ubushyuhe mu gutunganya peteroli/imiti. Iki gipimo kandi gikwiriye gukoreshwa mu buryo bwa hydraulic n'ibikoresho mu turere dushyuha two mu nyanja.
