Dab tsi yog qhov sib txawv ntawm 10 # steel yeeb thiab 20 # steel yeeb nkab?
Lub ntsiab sib txawv ntawm 10 # steel yeeb nkab thiab 20 # steel yeeb nkab yog lawv cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv mechanies. Cov hauv qab no yog qhov sib piv tshwj xeeb:
Tshuaj lom neeg cov tshuaj:
1 {0}}-steel yeeb nkab: cov ntsiab lus ntawm carbon yog nruab nrab ntawm {}}. 07% thiab 0.14%, feem ntau muaj tsawg dua cov khoom tawg loj.
2 {0, cov yeeb nkab steel: cov ntsiab lus ntawm {} thiab 0.24%, cov yeeb nkab carbon ntau dua 10 # steel yeeb nkab, yog li nws muaj zog dua thiab muaj zog.
Cov Khoom Siv Neeg Kho Tshuab:
10 # steel yeeb nkab: vim cov ntsiab lus roj carbon ntau dua, nws lub zog thiab hardness yog cov qes, tab sis kev du zog thiab siv vuam muaj txiaj ntsig zoo dua.
20 # Steel Yeeb: Muaj lub zog siab dua thiab qhov tsim nyog thiab haum rau cov khoom siv tau muaj zog thiab hardness, tab sis vuam lub zog yuav tsis zoo li 10 # steel yeeb nkab.
Hauv kev xyaum, kev xaiv ntawm cov yeeb nkab steel nyob ntawm cov kev xav tau tshwj xeeb ntawm daim ntawv thov. Piv txwv li, hauv cov ntawv thov uas xav tau lub zog siab dua thiab tawv tawv, xws li cov khoom siv hluav taws xob loj, 20 # steel yeeb nkab yog qhov kev xaiv tsim nyog dua. Whereas nyob rau hauv cov xwm txheej uas zoo weldability thiab ib co me ntsis ntawm kev sib txuas tawv, xws li cov yeeb nkab sib txuas, 10 # steel yeeb tuaj yeem tsim nyog dua.
