Qhov txawv ntawm Q235 thiab SS400 yog dab tsi?
Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg
SS400 (JIS G3101) thiab Q235 (GB / T700) yog ob qho tib si carbon structural steels, tab sis lawv cov ntsiab lus sib txawv. SS400 muaj cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.22% thiab qhov siab tshaj plaws ntawm sulfur / phosphorus impurity txwv ntawm 0.050%, thaum Q235B muaj cov ntsiab lus phosphorus tsawg dua lossis sib npaug rau 0.045% thiab cov ntsiab lus nqaim manganese ntau dua (0.30%-0.70%) tshaj li SS. Qhov kev tsim no ua rau Q235B ruaj khov nyob rau hauv hardenability nyob rau hauv lub kub dov lub xeev, tshwj xeeb tshaj yog haum rau precision pwm ua.
Mechanical Properties
Ob leeg muaj lub zog tensile ntawm 400-510 MPa, tab sis cov nyhuv thickness txawv heev. Lub zog tawm los ntawm SS400 txo qis qis dua nrog cov phab ntsa tuab (tsawg dua lossis sib npaug rau 16mm Ntau dua lossis sib npaug rau 245MPa, 16-40mm txo qis rau 235MPa), thaum Q235B muaj tus nqi nominal ntawm 235MPa tab sis nrog ntsuas qhov sib txawv ntawm ± 10MPa. Hais txog elongation, qhov sib txawv ntawm qhov tsawg kawg nkaus SS400 tus nqi ntawm 17% thiab tus qauv tus nqi ntawm Q235B ntawm 26% ncaj qha cuam tshuam rau stamping txoj kev txwv.
Kev tsim khoom
Compatibility Tseem ceeb qhov sib txawv ntawm vuam tsis: Nyob rau hauv cov xwm txheej ntawm 1.2 hli ER50-6 vuam hlau, SS400 yog haum rau 120-150A / 21-24V, thaum Q235B yuav tsum tau 150-180A. Thaum cov phab ntsa tuab tshaj 6 hli, SS400 yuav tsum tau 180A / 24V kom tswj tau qhov tob tob, thaum Q235B tuaj yeem tswj tau 150A / 22V hauv 8 hli. Nyob rau hauv cov txheej txheem machining, qhov hardness ranges ntawm ob (SS400: 120-160HB; Q235B: 140-180HB) ib nrab sib tshooj, tab sis Q235B muaj cov khoom zoo dua qub.
Daim ntawv thov Scenario
SS400 tuaj yeem hloov pauv hauv kev tsim kho, tab sis nws yuav tsum raug sau tseg tias SS400 tsis muaj qhov yuav tsum tau ua rau Z-axis kev ua haujlwm. Hauv kev tsim khoom siv tshuab, lub zog tensile siab ntawm SS400 yog qhov zoo rau cov khoom siv hauv tsev, thaum lub phosphorus tswj kom zoo dua ntawm Q235B tau txais txiaj ntsig corrosion kuj hauv cov khoom noj khoom haus. Tsav los ntawm qhov sib txawv ntawm kev sib sib zog nqus hauv kev lag luam tsheb, SS400 pickled steel sheet (SPHCP) yog hloov qee cov ntawv txias -rolled steel ntawv hauv chassis crossbeams.
