440C Ibyuma bitagira ibyuma

Icyuma cya 440C icyuma kidafite ingeso ni ubwoko bwicyuma kinini cya karubone. Imbaraga nyinshi, kurwanya ruswa hagati, gukomera neza no kwambara kurwanya. Icyiciro cya 440C kigera ku mbaraga nyinshi, gukomera no kwambara kurwanya ibyuma byose bitagira ingeso nyuma yo kuvura ubushyuhe. Ibirimo karubone nyinshi cyane niyo mpamvu yibi biranga, bituma 440C ikwiranye cyane cyane kubisabwa nkumupira hamwe nibice bya valve.

309/309S

309 na 309S ni austenitic chromium-nikel ibyuma bitagira ingeso mubisanzwe bikoreshwa mubushyuhe bwo hejuru. Bitewe na chromium nyinshi na nikel, 309 na 309S alloys ifite urwego rwo hejuru rwo kurwanya ruswa, Kurwanya okiside nziza hamwe no kurwanya ubushyuhe bwiza, mugihe utanga imbaraga nziza mubushyuhe bwicyumba nubushyuhe bwinshi. Itandukaniro rikomeye hagati ya 309 na 309S ni ibirimo karubone. Imiyoboro ya 309S ifite karubone nkeya, igabanya imvura ya karbide kandi ikatezimbere.

904L Ibyuma

Icyiciro cya 904L ni ibyuma bidahungabana na karubone. Kwiyongera kw'umuringa kuriyi cyiciro byongera cyane kurwanya aside ikomeye igabanya, cyane cyane aside sulfurike. Irwanya cyane igitero cya chloride, harimo kwangirika / crevice hamwe no kwangirika kwangira guhangayika.

347 Umuyoboro w'icyuma

347 ni ibyuma bihamye bya chromium, birimo niobium, bishobora gukuraho imvura ya karbide, bityo gukuraho kwangirika mumwaka. 347 yahagaritswe no kongeramo chromium na tantalum, kandi itanga imiterere yo hejuru no guhangayika imiterere kuruta alloys 304 na 304L, ishobora kandi gukoreshwa mugushishikaza no guhura nibibazo byangirika mumwaka. Kwiyongera kwa niobium nabyo bituma umuyoboro wa 347 ufite imbaraga nziza zo kwangirika, ndetse neza kuruta 321.

405 Ibyuma bitagira ibyuma

Imiterere yubukanishi yibyuma 405 bitagira umwanda ni ngombwa muguhitamo ibereye kubikorwa bitandukanye. Icyuma gifite akazi keza kandi biroroshye guca no gushushanya muburyo butandukanye. Byongeye kandi, ibikoresho byerekana urwego rwiza rwimbaraga no gukomera, bigatuma kwambara-birwanya kandi birwanya amarira. Ikintu kidasanzwe kiranga ibyuma 405 bidafite umwanda ni ubukana bwacyo, bivuga ubushobozi bwayo bwo guhinduranya munsi yumuvuduko utavunika. Uyu mutungo utuma icyuma gikwiriye gukora inzira nko kunama no kuzunguruka nta gucika cyangwa kumena.

303 Icyuma kidafite ibyuma

303 ibyuma bitagira ingeso nabyo byitwa 1.4305 ibyuma bitagira ingeso, icyiciro cya 303 nicyo cyoroshye gutunganya ibyuma byose bitagira umwanda. Imiterere ya machinability yo mucyiciro cya 303 iterwa no kuba sulfure mubintu byibyuma. Sulfure irashobora kunoza imashini, ariko ikagabanya kandi kurwanya ruswa no gukomera. Irwanya ruswa ryubwoko bwa 303 riri munsi yubwoko bwa 304, ariko ubukana buracyari nziza nkizindi manota ya austenitic.
