Tshuaj muaj pes tsawg leeg
X46: Feem ntau muaj cov ntsiab lus tseem ceeb xws li carbon, manganese, phosphorus, thiab sulfur. Cov ntsiab lus carbon feem ntau qis dua 0.24%, cov ntsiab lus manganese yog li 1.20%, thiab cov ntsiab lus phosphorus thiab sulfur yog tswj qis dua 0.030% raws li. Nws kuj tseem yuav muaj me me ntawm alloying ntsiab xws li niobium, vanadium, titanium, thiab lwm yam. Qhov sib ntxiv ntawm cov alloying ntsiab no pab ua kom cov nplej zoo dua thiab txhim kho lub zog thiab tawv ntawm cov yeeb nkab.
X65: Cov ntsiab lus carbon tsawg, feem ntau tsis tshaj 0. kuj tswj tau nyob rau theem qis, tsis pub tshaj 0.020% thiab 0.004% feem. Cov ntsiab lus ntawm cov ntsiab lus alloying xws li niobium, vanadium, titanium, thiab lwm yam kuj tseem txwv nruj, thiab tag nrho cov ntsiab lus ntawm cov ntsiab lus xws li chromium, npib tsib xee, tooj liab, thiab lwm yam. cev.
Mechanical zog
Yield zog: Qhov tsawg kawg nkaus tawm lub zog ntawm X46 yog 460MPa, thaum lub zog tsawg kawg nkaus ntawm X65 yog 531MPa. Lub zog tawm ntawm X65 yog qhov siab dua li ntawm X46, uas txhais tau hais tias X65 tuaj yeem tiv taus siab dua yam tsis muaj yas deformation.
Lub zog tensile: Lub zog tensile ntawm X46 feem ntau yog nruab nrab ntawm 530MPa-655MPa, thaum lub zog tensile ntawm X65 yog nyob nruab nrab ntawm 531MPa-655MPa. Lub zog tensile ntau ntawm ob qho tib si nyob ze, tab sis qis qis ntawm X65 txawv ntawm X46. Lub zog tawm los ntawm X46 yog sib npaug ntawm X65, uas txhais tau hais tias nws lub zog tag nrho yog siab dua.
Elongation: Qhov elongation ntawm X46 feem ntau tsis tsawg dua 20%, thiab qhov elongation ntawm X65 tsis tsawg dua 24%. X65 muaj zog dua thiab tswj tau zoo toughness.
Cov chaw thov
X46: Vim nws qhov sib npaug ntawm lub zog thiab lub zog, nws yog qhov tsim nyog rau qee cov kav dej uas tsis muaj kev xav tau tshwj xeeb siab, tab sis muaj qee qhov kev xav tau rau kev tiv thaiv corrosion thiab kev lag luam, xws li cov roj dav dav thiab cov roj hluav taws xob kis tau tus mob, thiab cov kua dej qis kis tau tus mob pipelines nyob rau hauv ib co industrial teb.
X65: Vim nws lub zog siab dua thiab zoo toughness, nws yog tsuas yog siv nyob rau hauv cov kav dej uas muaj kev kub siab thiab siab zog, xws li cov kav dej ntev thiab cov roj ntsha hauv lub cev, thiab cov roj thiab cov kav dej hauv qhov chaw hnyav xws li dej hiav txwv tob. thiab txias txias, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev thauj mus los ntawm cov dej ntws loj thiab kev kub siab.
