steel yeeb nkab ntau lawm txheej txheem
Cov txheej txheem ntawm cov yeeb nkab steel yog siv nrog rau kev siv tshuab ntawm 20G steel.
Steel yeeb nkab dimensional sib txawv thiab qhov hnyav sib txawv
Sab nraud txoj kab uas hla sib txawv: Sab nraud txoj kab sib txawv ntawm cov yeeb nkab steel yuav tsum ua tau raws li qhov yuav tsum tau ua

Phab ntsa thickness sib txawv: -8% ~ + 12%.
Qhov hnyav sib txawv: -3.5% ~ + 10%.
Taag-ntev qhov tseeb: raws li cov neeg siv khoom xav tau.
Ncaj: ≤1.5mm / / m.
Kev xa khoom thiab kev kho cua sov txheej txheem ntawm cov yeeb nkab steel
Cov yeeb nkab steel yog xa mus rau hauv lub xeev kev kho cua sov.
Cov txheej txheem kev kho cua sov ntawm cov khoom tiav yog: 900 ° C ~ 930 ° C rau 5 ~ 15min, cua txias.
Mechanical zog ntawm steel kav
Tensile zog
Lub zog tensile ntawm cov kav hlau yuav tsum ua tau raws li cov cai ntawm ASTM A333Gr6.
Rau cov kav hlau uas muaj cov phab ntsa nominal thickness ≤ 8 hli, cov qauv ntsuas tensile yog ib txoj kab uas hla ntev nrog qhov dav ntawm 12.5 hli thiab ntsuas qhov deb ntawm 50 hli. Rau cov kav hlau steel nrog lub nominal phab ntsa thickness ≥8mm, cov qauv puag ncig nrog qhov ntsuas qhov deb ntawm 4D tuaj yeem siv.
Flattening xeem
Lub crushing yam yog 0.07.
Kev cuam tshuam kev ua haujlwm
Txhua batch ntawm steel kav nrog ib tug txheej txoj kab uas hla ntau tshaj 21.3 hli yuav tsum tau soj ntsuam rau tej yam kev ua tau zoo Akv.

Impact test kub
Thaum lub thickness ntawm cov khoom me me me me mus txog los yog tshaj 80% ntawm qhov tseeb thickness ntawm cov yeeb nkab steel, qhov ntsuas kub yog -45 ° C.
Thaum lub thickness ntawm cov khoom me me me me yog tsawg dua 80% ntawm qhov tseeb tuab ntawm cov yeeb nkab steel, cov qauv tuab yuav tsum loj li sai tau. Qhov ntsuas kub yog -55 ° C.
Hardness test (tsuas yog thaum xav tau los ntawm daim ntawv cog lus)
Yog tias daim ntawv cog lus yuav tsum tau kuaj xyuas qhov nyuaj raws li NACE MR-0175 tus qauv, ib qho kev sim ntawm kwv yees li 20-30 hli ntev yuav tsum tau muab los ntawm txhua pawg ntawm cov kav hlau, thiab qhov hardness yuav tsum tsawg dua 22HRc.
