S235jr

S235jr
S235JR yog cov siv dav hlau nyob hauv European cov qauv qib hlau. Nws yog qhov tsis - Alloy alloy cov qauv hlau siv hauv kev tsim cov qauv steel thiab engineering cov qauv. Nws cov khoom galvanized (xws li kub - dip galvanized steel los) yog siv dav siv hauv kev tsim kho, kev tsim kho tshuab, thiab lwm daim teb. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm S235JR:
I. Cov Qauv Txheej Txheem
S235JR yog muab tau los ntawm European Cov Qauv EN 10025 {}}} 2 (kub-rolled cov khoom siv ntawm cov qhab nia hauv cov qauv ntawd. Nws sib thooj rau cov qauv zoo sib xws hauv cov txheej txheem thoob ntiaj teb (ISO) (piv txwv, S235JR zoo sib xws li 360 b hauv ISO 630).
Ii. Qib ntsiab lus
S: sawv rau "qauv steel."
235: Qhia rau cov hlau qis dua cov txiaj ntsig tsawg zog zog ntawm 235 MPa (rau thicknesses tsawg dua lossis sib npaug rau 16 hli). J: Qhia qhov kev cuam tshuam nyuaj sim ntsuas kub yog 20℃("j" sib piv rau 0℃mus rau 0℃mus rau -20 degree).
R: Qhia tau tias "kub -}} rolled" (dov).
III. Cov Khoom Tseem Ceeb
Tshuaj lom neeg sib xyaw ua ke (raug,%): C Tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug lossis sib npaug lossis sib npaug los ntawm 0.045 (cov ntsiab lus tshwj xeeb kom paub tseeb los ntawm tus qauv txheem).
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Tensile Lub Zog 360-510 MPa, elongation ntau dua los yog sib npaug rau 16 hli), cuam tshuam rau lub zog loj dua lossis sib npaug rau 27 degree.
Nta: du ua tau zoo heev, kev nruj heev, thiab weldability, tus nqi tsawg, haum rau cov qauv kev ua haujlwm. IV. Cov ntawv thov ntawm cov khoom Galvanized
S235JR yog ib qho uas siv tau siv cov khoom siv hluav taws xob kub rau kub- dip galvanized steel ntawv / kev ua raws li cov qauv galvanizing xws li en 10346). Nws cov khoom galvanized, xws li kub - dip galvanized s235jr galvanized s235jr galvanized s235jr galvc nrog corrosion tsis kam ntawm zinc txheej. Lawv tau siv dav hauv:
Cov qauv architectural steel (xws li nkhaus, tus saib xyuas, thiab ru tsev thauj khoom - Cov kabmob sib xyaw);
Tsis - precision cov qauv hauv tshuab tsim khoom nyob rau hauv kev tsim khoom machinery thiab cov cuab yeej tiv thaiv);
Sab nraum zoov engineering chaw (xws li txoj kev hlau thiab billboard nkhaus).
V. Tus Qauv Sib Tham
Tuam Tshoj GB / T 700: Q235B (kev ua tau zoo ib yam, cuam tshuam kub txog 20 degree);
Asmeskas Astm A36: Cov yam ntxwv zoo sib xws, feem ntau siv nyob rau hauv cov ntawv thov zoo sib xws;
Nyiv JIS GIS1011: SS400 (lub zog me ntsis, muaj peev xwm zoo ib yam li).
