S250GD yog dab tsi|1.0242 ib!
S250GD (1.0242) yog cov qauv steel qib raws li EN 10346, feem ntau yog siv rau cov hlau galvanized. "S" qhia txog cov qauv hlau, "250" qhia qhov tsawg kawg nkaus tawm lub zog hauv MPa, thiab "GD" qhia nws qhov tsim nyog rau galvanization. Nws muaj cov pa roj carbon, manganese, thiab silicon, nrog kev txwv nruj ntawm sulfur thiab phosphorus. Cov txheej txheem muaj xws li kub-dip thiab electro-galvanizing, tsim cov ntawv galvanized lossis coils rau kev tsim kho, khoom siv, thiab kev lag luam tsheb.

S250GD Steel nto kho hom
Peb muab ntau yam kev kho saum npoo kom tau raws li kev tiv thaiv sib txawv thiab kev xav tau zoo nkauj:
Chromating: Yog tias koj cov hlau yuav tsum raug rau qhov chaw ntub dej lossis corrosive ib puag ncig ntev, chromating tuaj yeem txhim kho corrosion kuj.
- Phosphate kho: haum rau tej yaam num uas yuav tsum tau tha xim, txhim khu xim adhesion thiab ua kom muaj zog xim nto.
- Oiling: muab kev tiv thaiv ib ntus los tiv thaiv- xeb tshwm sim thaum lub sijhawm khaws khoom thiab kev thauj mus los, tsim nyog rau cov hlau uas yuav tsum muaj kev tiv thaiv luv luv -.
- Painting: nce kev tiv thaiv thiab kev zoo nkauj. Yog tias koj qhov project muaj cov kev xav tau zoo nkauj rau cov tsos, koj tuaj yeem xaiv cov duab kos duab.
S250GD yog tus cwj pwm los ntawm kev sib xyaw ua ke ntawm lub zog, ductility thiab corrosion kuj. Qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 250 N / mm² thiab lub zog tensile nyob rau hauv thaj tsam ntawm 360-510 N / mm² lav ib tug txhim khu kev qha load- bearing muaj peev xwm nrog txaus ductility. Ua tsaug rau qhov kub -dip galvanized nto, cov hlau ua tiav kev tiv thaiv corrosion ntev, ua rau nws tiv taus txawm tias huab cua hnyav thiab ib puag ncig kev lag luam.
Qhov sib txawv npog variants muaj qhov zoo tshwj xeeb:
+ Z (ntshiab galvanized):
Txuj kev tiv thaiv corrosion rau dav dav.
+ZF (zinc{1}}hlau):
Txhim kho txheej adhesion thiab ua rau muaj zog tiv thaiv kev ntxhov siab.
+ZA (zinc-aluminium):
Optimized kuj nyob rau hauv atmospheric ib puag ncig.
+ZM (zinc{1}}magnesium):
Ntxiv kev tiv thaiv nyob rau hauv maritime thiab saline zones los ntawm passivating cwj pwm.
+ AZ (aluminium-zinc):
Kev sib xyaw ua ke ntawm kev tiv thaiv tshav kub thiab kev tiv thaiv corrosion, zoo tagnrho rau qhov kub thiab txias.
+AS (aluminium-silicon):
Tshwj xeeb tshaj yog rau cov ntawv thov nrog huab cua kub influences thiab siab corrosion loads.
