Spcc (Txias-rolled carbon hlau) yog ib hom khaub ncaws txias uas muaj cov khoom siv tshuab hluav taws xob uas tau yoog raws SPCC:
1. Dab tsi yog lub tensile lub zog?
Ntau yam: Kwv yees 270-410 MPa
(Tus nqi tshwj xeeb nyob ntawm cov khoom tuab thiab ua cov thev naus laus zis)
2. Dab tsi yog cov txiaj ntsig lub zog?
Ntau yam: ntau dua los yog sib npaug rau 140 mpa
(Qee cov tuam ntxhab lossis cov kev ua haujlwm tshwj xeeb yuav tsim cov nuj nqis ntau dua)
3. Dab tsi yog elongation?
A50 gauge ntev (tuab tsawg dua lossis sib npaug rau 0.25mm): ntau dua lossis sib npaug ntawm 28%
A80 gauge ntev (tuab> 0.25mm): ntau dua lossis sib npaug rau 34%
(Elongation yuav nce me ntsis nrog kev nce tuab)
4. Dab tsi yog lub hardness?
Vickers Hardness (HV): kwv yees li 60-150
Rockwell Hardness (HRB): kwv yees li 40-75
5. Lwm cov khoom siv
Yas yas: zoo, haum rau kev tsim cov txheej txheem xws li stamping thiab khoov.
Weldability: zoo, tab sis yuav tsum paub txog cov seem kev nyuaj siab uas tej zaum yuav muaj nyob tom qab dauv txias.
NCO TSEG: Kev ua tau zoo me me yuav sib txawv me ntsis nyob ntawm cov chaw tsim khoom, kev kho cua sov (piv txwv li kev kho mob), piv txwv li (piv txwv li, galvanizing)
