30CrMo umuyoboro wibyuma

Ibisobanuro bigufi:

Ibisobanuro ku musaruro:

Diameter yo hanze y'umuyoboro w'icyuma 20-426

Urukuta rw'icyuma rufite uburebure bwa 20-426

Kumenyekanisha ibicuruzwa:

Imibare ibiri mugitangiriro cyumubare wibyuma yerekana karubone yibyuma, hamwe nimpuzandengo ya karubone yibihumbi bike, nka 40Cr, 30CrMo umuyoboro wibyuma

Ibintu nyamukuru bivanga mubyuma, usibye ibintu bimwe na bimwe bya microalloying, mubisanzwe bigaragazwa nijana kwijana.Iyo impuzandengo ya alloy ibirimo iri munsi ya 1.5%, gusa ikimenyetso cyibintu kigaragara muri numero yicyuma, ariko ntabwo kirimo.Ariko, mubihe bidasanzwe, biroroshye kwitiranya, umubare "1 ″ urashobora gushyirwaho ikimenyetso nyuma yikimenyetso cyibintu, nkumubare wibyuma" 12CrMoV "na" 12Cr1MoV ", chromium yibya mbere ni 0.4-0,6%, naho ibya nyuma ni 0.9-1.2%.Ibindi byose ni bimwe.Mugihe impuzandengo ivanze yibigize ≥1.5%, ≥2.5%, ≥3.5% …… “, ikimenyetso cyibintu kigomba gushyirwaho ikimenyetso nyuma yibirimo, gishobora kugaragazwa nka 2, 3, 4 …… Ibikurikira, 18Cr2Ni4WA.

Ibintu bivanze nka vanadium V, titanium Ti, aluminium AL, boron B hamwe nubutaka budasanzwe RE mubyuma nibintu bya microalloying.Nubwo ibirimo ari bike cyane, bigomba gukomeza gushyirwaho nimero yicyuma.Kurugero, muri 20MnVB ibyuma.Vanadium ni 0.07-0.12% na boron ni 0.001-0.005%.

A “A” igomba kongerwaho nyuma yumubare wibyuma byo murwego rwohejuru kugirango itandukane nicyuma rusange cyiza cyane.

Intego idasanzwe ivanze ibyuma byubatswe, nimero yicyuma prefix (cyangwa umugereka) byerekana intego yikimenyetso.Kurugero, ibyuma 30CrMnSi bikoreshwa byumwihariko mugukoresha imigozi bigaragazwa nka ML30CrMnSi.

Ikoranabuhanga mu gukora:

1 → ububiko

2 ikizamini cya hydrostatike (ubugenzuzi) → ikimenyetso → ububiko
