Nyob rau hauv cov nqe lus ntawmatmospheric huab cua kev ua tau zoo thiab corrosion kujASTM A606-2 ua tau zoozoo ib yam li feem ntau cov qauv txheej txheem huab cua steelsnyob rau hauv ib puag ncig sab nraum zoov inland. Qhov sib txawv yog feem ntau nyob rau hauv daim ntawv ntawm cov khoom, lub zog, thiab daim ntawv thov, tsis yog nyob rau hauv lub hauv paus ntawm corrosion cwj pwm.
1. Muab piv nrog ASTM A588 Qib B
Huab cua kev ua haujlwmA606-2 thiab A588 Gr.B muajyuav luag zoo tib yam atmospheric corrosion kuj.Ob leeg cia siab rau tib qhov tseem ceeb alloying system (Cu, Cr, Ni, Si) tsim kom muaj qhov ntom ntom, tiv thaiv, ruaj khov patina uas inhibits ntxiv corrosion.
Qhov txawv: A588 Gr.B yog tsim los rauhnyav structural seem thiab tuab daim hlau, thaum A606-2 yog tsim raws linyias daim ntawv thiab coilnrog zoo dua nto tiav.Lawv lub sij hawm ntev huab cua tus cwj pwm thiab durability sab nraum zoov yog qhov tseem ceeb sib npaug.
2. Piv nrog Corten-A / Corten-B
Huab cua kev ua haujlwmCorten-A yog tshuaj lom neeg thiab ua haujlwm zoo ib yam li A588 Gr.B, yog li nws cov huab cua ua haujlwm yogpiv rau A606-2.Corten-B muaj zog dua me ntsis tab sis zoo li corrosion kuj.
Xaus: A606-2 sib tw Corten-A hauv huab cua ua haujlwm ntev thiab kev loj hlob patina hauv ib puag ncig sab nraum zoov.
3. Piv nrog A606 Hom 4 / Hom 5 (siab dua-alloy variants)
Huab cua kev ua haujlwm: Hom 4 thiab Hom 5 muaj cov qib siab dua ntawm chromium, npib tsib xee, thiab tooj liab kom txhim kho kev tiv thaiv hauv kev lag luam lossis ib puag ncig corrosive me ntsis.A606-2 muajstandard weathering kev ua tau zoo, uas yog tag nrho txaus rau feem ntau toj roob hauv pes, architectural, thiab dav siv sab nraum zoov.
4. Muab piv nrog cov hlau tsis muaj zog (piv txwv li, SPA-H, SPA-C)
Huab cua kev ua haujlwm: Cov qib no kuj tsim muaj kev tiv thaiv patina thiab qhia tau zoo atmospheric durability.Lawvcorrosion kuj zoo ib yam li A606-2, tab sis lawv muaj zog mechanical zog.
Qhov txawv: A606-2 muabmuaj zog ntau dua thiab kev ua haujlwm zoothaum tuav tib theem ntawm huab cua kev ua tau zoo.
