304 316L 2205 S31803 Isahani idafite ibyuma
Kwerekana ibicuruzwa:
Kurwanya kwangirika kwibyuma bitagira umwanda biterwa ahanini nuburinganire bwayo (Cr, Ni, Ti, Si, Al, Mn, nibindi) hamwe nimiterere yimbere.
Ukurikije uburyo bwo gukora bwo gushyushya ubushyuhe no gukonjesha bikonje ubwoko bubiri, ukurikije ibiranga tissue biranga ubwoko bwibyuma bigabanijwemo ibyiciro 5: ubwoko bwa austenite, ubwoko bwa austenite-ferrite, ubwoko bwa ferrite, ubwoko bwa martensite, ubwoko bwimvura igwa.
Isahani idafite ibyuma isa neza, ifite plastike nyinshi, ubukana nimbaraga za mashini, kurwanya aside, gaze ya alkaline, igisubizo nibindi byangirika mubitangazamakuru.Nicyuma kivanze kitangirika byoroshye.

SA588 SA387 Isahani y'icyuma
Kwerekana ibicuruzwa:
Ukurikije ibikubiye mubintu bivanze bigabanijwemo:
ibyuma bito bito (umubare wibintu byose bivanze ni munsi ya 5%),
Hagati yicyuma giciriritse (5% -10% yibintu byose bivanze)
Ibyuma binini cyane (ibintu byose bivanze birenze 10%).
Ukurikije ibice bigize ibice bigize:
Ibyuma bya Chromium (Cr-Fe-C)
Chromium-nikel ibyuma (Cr-Ni-Fe-C)
Icyuma cya Manganese (Mn-Fe-C)
Silicon-manganese ibyuma (Si-Mn-Fe-C)

Isahani irwanya isahani, Ikirere kirwanya ikirere
Kwerekana ibicuruzwa:
Isahani idashobora kwangirika igizwe n'ibice bibiri: icyuma gike cya karuboni nkeya hamwe n'icyuma gishobora kwihanganira kwambara.Umuti wihanganira kwambara ni 1/3 ~ 1/2 cyubugari bwuzuye.Iyo ikora, matrix itanga imikorere yuzuye nkimbaraga, ubukana hamwe na plastike, hamwe na alloy yambara idashobora kwihanganira kwambara kugirango ihuze ibisabwa kugirango akazi gakorwe.
Imyenda idashobora kwangirika cyane ni chromium alloy, kandi manganese, molybdenum, niobium, nikel nibindi bikoresho bivangwa nabyo byongeweho.Carbide mumyuma ya metallografiya ikwirakwizwa muburyo bwa fibre, kandi icyerekezo cya fibre ni perpendicular kubuso.Microhardness ya karbide irashobora kugera hejuru ya HV1700-2000, kandi ubukana bwubuso bushobora kugera HRC 58-62.Alloy karbide ifite ituze rikomeye mubushyuhe bwo hejuru, ikomeza ubukana bwinshi, ariko kandi ifite antioxydants nziza, muri 500 use ikoreshwa bisanzwe.

Isahani yicyuma igabanijwemo amasahani ashyushye kandi akonje.
Ukurikije ubwoko bwibyuma, hariho ibyuma bisanzwe, ibyuma byujuje ubuziranenge, ibyuma bivanze, ibyuma byamasoko, ibyuma bidafite ingese, ibyuma byuma, ibyuma birwanya ubushyuhe, bitwaje ibyuma, ibyuma bya silikoni hamwe nu rupapuro rwicyuma.
Ibyuma bya karubone byujuje ubuziranenge birashobora kugabanywamo ibyiciro bitatu ukurikije ibintu bitandukanye bya karubone: ibyuma bya karubone nkeya (C 0,25%), ibyuma bya karubone yo hagati (C ni 0,25-0,6%) hamwe nicyuma kinini cya karubone (C & gt; 0,6%).
Ibyuma bya karubone byujuje ubuziranenge bigabanijwemo manganese isanzwe (0,25% -0.8%) na manganese yo hejuru (0,70% -1,20%), iyanyuma ifite imiterere yubukanishi nuburyo bwo gutunganya.
