S250GD Galvanized hlau
S250GD galvanized steel ntawv / phaj yog qis- alloy, siab-lub zog kub- dov steel, feem ntau siv hauv kev tsim kho, tsheb, thiab khoom siv hauv kev lag luam. Nws cov khoom tseem ceeb suav nrog hlau thiab cov ntsiab lus carbon tsawg, feem ntau ntawm 0.06%-0.12%. Cov ntawv hlau / phaj yog coated nrog zinc txheej los ntawm kub-dip galvanizing, uas muab ib qho kev tiv thaiv zoo tiv thaiv corrosion.
Nrog lub zog tensile ntawm 250 MPa, S250GD tuaj yeem tswj cov kev ntxhov siab tseem ceeb. Cov txheej zinc txhim kho nws cov kav ntev, ua rau nws tsim nyog rau kev siv sab nraum zoov thiab txuas ntxiv cov khoom lag luam thaum txo cov kev xav tau ntawm kev saib xyuas.
Cov khoom
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 cov xwm txheej.
- +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.
