Qhov txawv ntawm SS400 thiab Q235B yog dab tsi?
Qhov taw tes tawm ntawm Q235 yog ntau dua 235 MPa hauv peb lub teb chaws tus qauv, thaum lub ntsiab lus ntawm SS400 yog 245MPa. Qhov no yog qhov sib txawv ntawm cov txiaj ntsig, SS400 steel rau cov qauv dav dav yog cov qauv hlau dav dav nrog lub zog tensile siab dua 400MPa.
SS400 yog dab tsi
SIB 400yog cais raws liRolled Steel rau General Structuresub osJapanese Industrial Standard JIS G3101, thiab yog ibcarbon steel yeeb nkabnrog ayield zog Ntau tshaj los yog sib npaug rau 245 MPa.
Q235B yog dab tsi
Q235B steel yeeb nkabyog aQib B carbon structural steel yeeb nkabua raws li covSuav National Standard GB / T 700. Nws yog manufactured siv ib tugtua hlau txheej txheem(Deoxidized: Killed Steel), nrog rauyield zog Ntau tshaj los yog sib npaug rau 235 MPa, thiabYuav tsum muaj kev cuam tshuam toughness(Ntau dua lossis sib npaug rau 27J ntawm 20 degree). Cov khoom siv no haum rau kev pabcuam ib puag ncigsaum toj no -20 degree.

Core Application Areas
Lub Tsev Load-Cov Qauv Kabmob
Dynamic Load Frames: Choj kev txhawb nqa, Hoobkas lub tsev girders (yuav tsum muaj ntau dua lossis sib npaug rau 27J cuam tshuam lub zog ntawm 20℃rau seismic tsis kam - Q235A txwv)
Secondary Floor Beams: Siv cov yas kom nqus tau lub zog deformation (tus nqi qis dua piv rau ASTM A36)
Pipe Piles & Foundation Engineering
ASTM A252 Yeeb Nkab Pile Connectors(raws li cov ntsiab lus ua ntej):
Lub Cev Lub Cev Loj: A252 Gr.3 (Yield Ntau dua lossis sib npaug rau 414 MPa)
Connector Rings / Flanges: Q235B (235 MPa tawm los, toughness rau dynamic loads)
Cov khoom siv hauv paus thauj tog rau nkoj bolts (kev pabcuam temp. Ntau dua lossis sib npaug rau -20 degree)
Cov Khoom Siv Hluav Taws Xob
Engineering machinery chassis (tsis yog- cov khoom tseem ceeb rau cov khoom siv excavators / cranes)
Cia khib uprights (tus nqi zoo tshaj -kev ua haujlwm zoo li qub)
Lub zog xa hluav taws xob (kev pabcuam temp.> -20 degree, outperforms SS400's -5℃txwv)
Ntim thiab shipping
