Garanti yo kugurisha 30CrMo alloy ibyuma bikora ibyuma
30CrMo umuyoboro wibyuma ufite karubone irimo 0.26 ~ 0.34, silikoni ya 0.17 ~ 0.37, manganese ya 0.40 ~ 0.70, molybdenum ya 0.15 ~ 0.25, chromium ifite 0.80 ~ 1.10. Hariho umubano yombi no gutandukanya imiyoboro ya aliyumu n'umuyoboro udafite kashe, bidashobora kwitiranywa. Umuyoboro wa Alloy usobanurwa nkumuyoboro wibyuma ukurikije ibikoresho (ni ukuvuga ibikoresho). Nkuko izina ribigaragaza, ni umuyoboro wakozwe mu mavuta; Umuyoboro udafite icyerekezo usobanurwa ukurikije uburyo bwo gukora umuyoboro wibyuma (seamless seam). Ibitandukanye n'umuyoboro udafite ikidodo ni umuyoboro udafite ikidodo, harimo umuyoboro usudutse ugororotse hamwe n'umuyoboro uzunguruka. 35CrMo, 16-50mn, 27SiMn, 40Cr, Cr5Mo 12Cr1MoV 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 30CrMo 35crmov 40CrMo 45crmoo 40CrMo 45crmoo P22.p91.

Urwego rw'icyuma, mu magambo ahinnye nk'icyuma, ni izina rya buri gicuruzwa cyihariye. Ni ururimi rusanzwe kubantu bumva ibyuma. Mu Bushinwa, ikimenyetso gikaze kigaragazwa cyane no guhuza inyuguti za Pinyin zo mu Bushinwa, ibimenyetso bya shimi n’imibare y’icyarabu.
Ibikurikira, tuzamenyekanisha ibisobanuro byibintu nibimenyetso mubyuma
Imibare ibiri mugitangiriro cyicyiciro cyerekana ibyuma byerekana karubone yibyuma, bigaragazwa nkibihumbi bike byikigereranyo cya karubone, nka 40Cr.
Ibintu nyamukuru bivanga mubyuma, usibye ibintu bya microalloyed yibintu, mubisanzwe bigaragarira mubice bike. Iyo impuzandengo ya aliyumu iri munsi ya 1.5%, murwego rwicyuma
Mubisanzwe, ikimenyetso cyibintu cyonyine kirangwa, ariko ibirimo ntabwo byashyizweho ikimenyetso. Ariko, niba byoroshye kwitiranya mubihe bidasanzwe, umubare "1" urashobora kandi gushyirwaho ikimenyetso nyuma yikimenyetso,
Kurugero, kumanota yicyuma "12CrMoV" na "12Cr1MoV", chromium yibya mbere ni 0.4-0,6%, naho iyanyuma ni 0.9-1.2%, nibindi bice byose ni bimwe
Iyo impuzandengo y'ibintu bivanze ni ≥ 1.5%, ≥ 2,5%, ≥ 3.5% ... Ibirimo bizerekanwa nyuma yikimenyetso cyibintu, bishobora kugaragazwa nka 2 na 3 bikurikije
alloy
Amavuta (impapuro 2)
Urugero, 18Cr2Ni4WA.
Vanadium V, titanium Ti, aluminium Al, boron B, isi idasanzwe RE nibindi bintu bivangwa mubyuma ni ibintu bya microalloyed. Nubwo ibirimo biri hasi cyane, bigomba kuba mubyiciro byibyuma
Ikimenyetso. Kurugero, muri 20mnvb ibyuma, vanadium ni 0.07-0.12% na boron ni 0.001-0.005%.
Ibyuma byujuje ubuziranenge bigomba gushyirwaho "a" nyuma yicyiciro cyicyuma kugirango gitandukane nicyuma rusange cyiza.
Kubyuma byubaka ibyuma kubwintego yihariye, urwego rwicyuma rubanzirizwa na (cyangwa umugereka) kugirango ugereranye ikimenyetso cyintego yicyuma. Kurugero, 30CrMnSi ibyuma byo kuzunguruka,
Urwego rwicyuma rwerekanwa nka ml30crmnsi.
Kubuhanga buke buke buvanze cyane ibyuma, bizerekanwa nyuma yicyiciro cyicyuma. Kurugero, 16Mn ibyuma, ibyuma bidasanzwe bikoreshwa mubiraro ni "16Mnq", icyuka
Icyiciro cyihariye cya girder ni "16MnL", naho icyiciro cyihariye cyicyuma cyumuvuduko ni "16MnR".
