347 Icyuma
Ibyuma bitagira umwanda 347 ni titanium - itajegajega ya austenitike idafite ibyuma, itandukanijwe no kurwanya bidasanzwe kwangirika kw’imitsi nyuma yo guhura n’ubushyuhe bwinshi, cyane cyane mu gusudira no gutunganya ubushyuhe. Iyi mavuta yakozwe kugirango ikemure ibibazo byimvura ya karbide ikunze kugaragara mu ntera ya - itajegajega amanota ya austenitis, bigatuma ihitamo ryizewe mubisabwa birimo serivisi yubushyuhe bumaze igihe kirekire.

Ibyuma bitagira umwanda 347 ni titanium - itajegajega ya austenitike idafite ibyuma, itandukanijwe no kurwanya bidasanzwe kwangirika kw’imitsi nyuma yo guhura n’ubushyuhe bwinshi, cyane cyane mu gusudira no gutunganya ubushyuhe. Iyi mavuta yakozwe kugirango ikemure ibibazo byimvura ya karbide ikunze kugaragara mu ntera ya - itajegajega amanota ya austenitis, bigatuma ihitamo ryizewe mubisabwa birimo serivisi yubushyuhe bumaze igihe kirekire.
Inyungu yibanze ya 347 ni ukurwanya kwangirika kw’imitsi, ndetse na nyuma yo kumara igihe kinini ubushyuhe buri hagati ya dogere 425 - 815 (800 - 1500 dogere F). Ibi bituma biba byiza muburyo bwo gusudira bukora ku bushyuhe bwinshi, kuko bivanaho gukenera post - weld annealing mubisabwa byinshi. Itanga kandi uburyo bwiza bwo kurwanya ruswa mu bidukikije byo mu kirere, amazi meza, hamwe n’ibisubizo byinshi by’imiti, nubwo irwanya imyanda iterwa na chloride igereranywa na 304 aho kuba amanota yongerewe na molybdenum nka 316.

Iyi niobium - itajegajega ibyuma bya austenitike itagira ibyuma byongera imbaraga zo kurwanya ruswa hamwe n’imikorere yubushyuhe bwo hejuru - binyuze muri niobium. Niobium ihitamo cyane hamwe na karubone kugirango ikore karbide ihamye, irinde neza kugabanuka kwa chromium mubushyuhe bwo gukangurira (425 ~ 860 dogere). Ibi bituma bikenerwa cyane cyane kubikoresho byo gusudira hamwe nubushyuhe bwo hejuru - (ubushyuhe bwa serivisi ntarengwa: dogere 900). Mugihe hagaragajwe imbaraga zo kurwanya ruswa mu itangazamakuru rya okiside, irwanya chloride ihangayikishije ikomeza kuba mike. Ibikoresho ntabwo - magnetique mugisubizo - imiterere idahwitse.
Porogaramu
Hejuru - Ibikoresho by'ubushyuhe: Amashanyarazi, guhinduranya ubushyuhe, ibice bya moteri yindege (serivisi ndende - serivisi yigihe kiri munsi ya dogere 800)
Inganda zikora imiti:Acide ikomeye - ibikoresho bidashobora kwihanganira, imiyoboro isudira (nta poste - kuvura ubushyuhe busabwa)
Urwego rw'ingufu:Ibikoresho bya kirimbuzi imbere, ibice bya peteroli
Inganda zitwara ibinyabiziga:Inzu ya Turbocharger, sisitemu yo gusohora
Ibirangantego: 347 ibyuma bidafite ingese, Ubushinwa 347 abakora ibyuma, abatanga ibicuruzwa, uruganda
