ASTM-SA516Gr60Z35 icyuma cyerekana icyuma:
1. SA516Gr60 yubuyobozi bukuru: ASTM y'Abanyamerika, ASME
2. SA516Gr60 ni iyumuvuduko ukabije wubushyuhe hamwe nicyuma cya karubone
3. Ibigize imiti ya SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Imiterere ya mashini ya SA516Gr60
SA516Gr60 imbaraga zingana zingana na pound ibihumbi 70 / santimetero kare, ibyingenzi nyamukuru ni C Mn Si ps igenzura imikorere yayo.Ibindi bikoresho byo hasi.Asme Igipimo cyerekana ibyuma bya karubone kubikoresho byo hagati yubushyuhe bwo hasi.
5. Imiterere yo gutanga ya SA516Gr60
Isahani ya SA516Gr60 isanzwe itangwa muburyo buzunguruka, isahani yicyuma nayo irashobora kuba ibisanzwe cyangwa kugabanya imihangayiko, cyangwa mubisanzwe wongeyeho gahunda yo kugabanya ibibazo.
SA516Gr60 uburebure> 40mm isahani yicyuma igomba kuba isanzwe.
Keretse niba byavuzwe ukundi nuwabisabye, ubunini bwicyuma cya plaque .51.5in, (40mm), mugihe hari ibisabwa bitagoranye, bigomba kuba bisanzwe.
6Ikoreshwa cyane muri peteroli, inganda z’imiti, sitasiyo y’amashanyarazi, amashyiga n’indi mirimo, ikoreshwa mu gukora reakteri, guhanahana ubushyuhe, gutandukanya, ibigega bya serefegitura, ibitoro bya peteroli na gaze, ibigega bya gaze ya lisansi, ingoma ya boiler, amavuta y’amavuta ya peteroli, sitasiyo y’amashanyarazi imiyoboro y'amazi yumuvuduko mwinshi, turbine volute nibindi bikoresho nibigize.
7. Iyo austenite ikonje buhoro (bihwanye no gukonjesha itanura, nkuko bigaragara ku gishushanyo cya 2 V1), ibicuruzwa bihinduka byegereye imiterere iringaniye, aribyo pearlite na ferrite.Hamwe n'ubwiyongere bw'igipimo cyo gukonja, ni ukuvuga, iyo V3> V2> V1, gukonjesha kwa austenite bigenda byiyongera buhoro buhoro, kandi umubare wa ferrite yaguye ugenda ugabanuka, mu gihe ingano ya pearlite yiyongera buhoro buhoro, kandi imiterere ikaba nziza.Muri iki gihe, ferrite yimvura yagabanijwe ahanini ikwirakwizwa kumupaka wingano.
8. Kubwibyo, imiterere ya v1 ni ferrite + pearlite;Imiterere ya v2 ni ferrite + sorbite;Microstructure ya v3 ni ferrite + troostite.
9. Iyo igipimo cyo gukonja ari v4, umubare muto wa net ferrite na troostite (rimwe na rimwe hashobora kuboneka umubare muto wa bainite) urashobora kugwa, kandi austenite ihinduka cyane muri martensite na troostite;Iyo igipimo cyo gukonja v5 kirenze igipimo gikomeye cyo gukonjesha, ibyuma bihinduka rwose muri martensite.
10. Guhindura ibyuma bya hypereutectoid bisa nibyuma bya hypoeutectoid, hamwe nibitandukaniro ferrite igwa mbere mubyanyuma naho simaite igwa mbere mubyambere.
