Ibyuma bisanzwe birwanya ubushyuhe bitagabanijwe mubisanzwe bigabanijwemo ubwoko butatu, 309S, 310S na 253MA, ibyuma birwanya ubushyuhe bikunze gukoreshwa mugukora amashyiga, amashyanyarazi, itanura ryinganda nindege, peteroli na chimique nizindi nganda mubushyuhe bwo hejuru bukora ibice.
1.309s: (OCr23Ni13) icyuma kidafite ingese
Ibiranga: Irashobora kwihanganira ubushyuhe buri munsi ya 980 ℃, hamwe nubushyuhe bwo hejuru bwo hejuru, kurwanya okiside hamwe no kurwanya karburize.
Gushyira mu bikorwa: ibikoresho by'itanura, birashobora gukoreshwa mugukora ibyuma bishyushye, Chromium nini hamwe na nikel itanga imbaraga zo kurwanya ruswa no kurwanya okiside.
Ugereranije na austenitis 304 alloy, irakomera gato mubushyuhe bwicyumba.Mubuzima busanzwe, irashobora gushyuha inshuro 980 ° C kugirango ikomeze imirimo isanzwe.310s: (0Cr25Ni20) icyuma kidafite ingese.
2.310s: (OCr25Ni20) icyuma kidafite ingese
Ibiranga: Chromium-nikel yo hejuru ya austenitis ibyuma bitagira umuyonga hamwe nubushyuhe bwiza bwo mu rwego rwo hejuru kandi birwanya ruswa mu itangazamakuru ryangiza.Bikwiranye no gukora ibice bitandukanye byitanura, ubushyuhe bwo hejuru 1200 ℃, guhora ukoresha ubushyuhe 1150 ℃.
Gusaba: ibikoresho by'itanura, ibikoresho byoza imodoka.
310S ibyuma bitagira umwanda nicyuma cyangirika cyane cya austenitis cyuma kitagira ibyuma bikoreshwa mubushyuhe butandukanye bwo hejuru kandi bwangirika.Ni amahitamo meza kubisabwa mubikorwa bya peteroli, imiti, nubushyuhe butunganya ubushyuhe, kimwe nibice bigize itanura nibindi bikoreshwa mubushyuhe bwo hejuru.Isahani ya 310S idafite isahani ni urupapuro ruto, ruto rukozwe muri iyi mavuta yihariye.
3.253MA (S30815) icyuma kidafite ingese
Ibiranga: 253MA nicyuma cyihanganira ubushyuhe bwa Austenitike ibyuma bidafite ibyuma bigenewe porogaramu zisaba imbaraga zinyanja nini kandi zirwanya ruswa.Ubushyuhe bwacyo bukora ni 850-1100 ℃.
253MA ni ubwoko bwihariye bwibyuma bidafite ibyuma byashizweho kubushyuhe bwo hejuru.Itanga imbaraga nziza zo kurwanya okiside, sulfide, na karburizasi ku bushyuhe bwo hejuru.Ibi bituma ikoreshwa mu nganda zinyuranye, zirimo iz'ubushyuhe na ruswa, nka peteroli, amashanyarazi, n’amashyanyarazi y’inganda.Impapuro 253MA ni ntoya, ibice byibikoresho bikozwe muri iyi mavuta.Zikoreshwa mubikorwa bitandukanye aho guhuza ubushyuhe bwo hejuru hamwe no kurwanya ruswa ni ngombwa.Impapuro zirashobora gutemwa no gukorwa muburyo butandukanye kugirango zuzuze ibisabwa byumushinga.

253MA Kurwanya Isahani Kurwanya no gukoresha ibidukikije:
1. Kurwanya ruswa: 253MA ifite imbaraga zo kurwanya okiside nziza, kurwanya ubushyuhe bwo hejuru cyane, hamwe nimbaraga zidasanzwe zubushyuhe bwo hejuru.Ifite akamaro cyane mubushyuhe bwa 850 kugeza 1100 ° C.
2.Ubushyuhe: Kubikorwa byiza, 253MA ikwiranye no gukoreshwa mubushyuhe bwa 850 kugeza 1100 ° C.Ku bushyuhe buri hagati ya 600 na 850 ° C, impinduka zubatswe zirabaho, bigatuma kugabanuka gukomeye kwubushyuhe bwicyumba.
3.Imbaraga za mashini: Iyi mavuta irenze ibyuma bisanzwe bitagira umwanda, nka 304 na 310S, ukurikije imbaraga zigihe gito cyigihe gito mubushyuhe butandukanye hejuru ya 20%.
4.Imiterere yimiti: 253MA igaragaramo imiti iringaniye itanga imikorere idasanzwe mubushyuhe bwa 850-1100 ° C.Yerekana imbaraga nyinshi cyane zo kurwanya okiside, hamwe nubushyuhe bugera kuri 1150 ° C.Itanga kandi imbaraga zo hejuru zirwanya imbaraga hamwe no kuvunika imbaraga.
5. Kurwanya ruswa: Usibye ubushobozi bwubushyuhe bwo hejuru, 253MA yerekana imbaraga zirwanya ruswa yubushyuhe bwo hejuru hamwe na ruswa ya ruswa mubidukikije byinshi.
6.Imbaraga: Ifite imbaraga nyinshi z'umusaruro n'imbaraga zingana n'ubushyuhe bwo hejuru.
7.Formability and Weldability: 253MA izwiho kuba nziza, gusudira, hamwe na mashini.
