SPCE Steels yog dab tsi?
SPCE sib sib zog nqus kos duab zoo txias dov hlau yog sib sib zog nqus nqus zoo txias dov steels, uas yog siv rau daim ntaub ntawv. Cov khoom siv no siv tau rau kev kos duab ua haujlwm qhov twg qhov tob ntawm qhov kos tau tshaj nws txoj kab uas hla.
Dimensional Yam ntxwv ntawm SPCE Steels: Lub thickness tsim nyog rau qhov no SPCE sib sib zog nqus nqus cov khoom zoo txias dov steel khoom raws li demarcated hauv JIS G3141 pib ntawm 0.25 hli mus rau 2.5 hli. Txawm li cas los xij, qhov dav ntawm SPCE cov khoom muaj nyob rau ntawm 2000 hli.
Lub Chemical Composition ntawm SPCE sib sib zog nqus nqus tau zoo txias dov steels: JIS G 3141 piav qhia txog cov tshuaj muaj pes tsawg leeg ntawm SPCE steels raws li hauv qab no:
Qhov feem pua siab tshaj ntawm Carbon (C) yog 0.10 feem pua.
Qhov feem pua siab tshaj ntawm Manganese (Mn) yog 0.45 feem pua.
Qhov feem pua siab tshaj ntawm Phosphorous (P) yog 0.030 feem pua.
Qhov feem pua siab tshaj plaws ntawm Sulfur (S) yog 0.030 feem pua.
Sab laug yog hlau (Fe) feem pua thiab nrog ob peb tsis pom zoo impurities.
Qib | C | Mn | P | S |
SPCE | Tsawg dua lossis sib npaug rau 0.10 | Tsawg dua lossis sib npaug rau 0.45 | Tsawg dua lossis sib npaug rau 0.030 | Tsawg dua lossis sib npaug rau 0.030 |
Mechanical Properties ntawm SPCE sib sib zog nqus nqus qhov zoo txias dov hlau:
Hauv qab no yog qee qhov kev ua haujlwm ntawm SPCE steels:
Lub zog tensile ntawm SPCE Steels qhia nyob rau hauv Newton ib millimeters thiab nws yuav tsum yog tsawg kawg yog 270 N / mm2 (MPa), thaum lub zog tawm los yog siab tshaj 220 N / mm2 (MPa).
Cov cuab yeej elongation ntawm SPCE steel sib txawv nrog ntau qhov tuab.
Qhov feem pua ntawm qhov tsawg kawg nkaus rau elongation yog los ntawm 32 mus rau 43 feem pua, pib ntawm 0.25 hli mus rau 2.5 hli thiab tshaj.
Weld peev xwm ntawm cov ntaub ntawv no yog conformed.
SPCE steels tuaj yeem kos rau qhov tob dua thiab hloov tau yooj yim dua li piv rau SPCD steels.
