I. Ib puag ncig qhuav sab hauv tsev
Cov Khoom Pom Zoo: Ordinary Carbon Steel Bolts
Qhov zoo: Tus nqi qis, kev ua haujlwm yooj yim, qib zog npog 4.8-12.9, ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv sab hauv feem ntau txhim kho thiab kev sib dhos dav dav.
Kev ceev faj: Tsis tas yuav tsum muaj kev kho mob ntxiv rau kev tiv thaiv corrosion. Tsis txhob siv sijhawm ntev - nyob rau hauv qhov chaw ntub dej kom tiv thaiv oxidation sai thiab xeb.
II. Humid/Ordinary Sab nraum Ib puag ncig
Cov khoom pom zoo: 304 (A2) Stainless Steel Bolts
Qhov zoo: Ntxiv chromium thiab npib tsib xee cov ntsiab lus tsim ib zaj duab xis passivation, muab kev xeb zoo dua piv rau cov hlau, thiab tuaj yeem tiv taus txhua hnub noo noo thiab nag corrosion.
Siv tau Scenarios: Sab nraum zoov railings, sam thiaj rooj tog, dav siv sab nraum zoov kho, thiab lwm yam.
III. Siab ntsev tsuag / ntug dej hiav txwv / Muaj zog Corrosive ib puag ncig
Cov Khoom Pom Zoo: 316 (A4) Stainless Steel Bolts
Qhov zoo: Ntxiv 2%-3% molybdenum cov ntsiab lus, ua kom cov tshuaj chloride corrosion ntau dua 3 zaug piv rau 304, thiab muab kev tiv thaiv ntev rau dej hiav txwv thiab ntsev tsuag corrosion.
Cov xwm txheej siv tau: Lub nkoj decks, kev txhawb nqa ntawm ntug dej hiav txwv photovoltaic, thiab kev sib txuas rau cov khoom siv nyob ib puag ncig cov chaw cia khoom.
IV. Hnyav-Lub luag haujlwm/siab-Tsub/High-Hloov siab
Cov khoom pom zoo: Alloy steel bolts (xws li, 40Cr, 35CrMo, 42CrMo)
Qhov zoo: Nrog rau qhov sib ntxiv ntawm cov ntsiab lus alloying xws li chromium thiab molybdenum, tom qab quenching thiab tempering, lub zog tuaj yeem ncav cuag qib 8.8 lossis siab dua, nrog qhov siab tshaj plaws ntawm qib 12.9. Kev ruaj ntseg zoo heev nyob rau hauv qhov kub ntawm -50℃mus rau 300 degree, thiab qaug zog tsis kam yog 2-3 zaug ntawm carbon hlau.
Muaj feem xyuam: Hnyav- lub luag haujlwm tsheb chassis, cua turbine lub ntsiab shafts, siab - qhov kub siab ntawm cov hlab ntsha, siab - kev sib txuas ntawm cov kav dej flange, thiab lwm yam tseem ceeb thauj khoom - cov kabmob.
V. Cov xwm txheej tshwj xeeb
Marine High-Corrosion Lifting Scenarios: Siv cov khoom siv tshwj xeeb alloy shackles thiab txuam alloy steel bolts, ntsuas lub zog siab thiab ua haujlwm rau marine corrosion.
Muaj zog Acid thiab Alkali Chemical Conditions: Siv cov khoom siv tshwj xeeb alloy bolts nrog cov kua qaub thiab alkali tiv thaiv kom tsis txhob muaj cov hlau tsis zoo ib yam los ntawm kev raug corroded los ntawm cov tshuaj lom neeg, ua kom ntev - lub sij hawm sealing stability.
Kev siv lub teeb yuag / Aerospace: Titanium alloy bolts raug xaiv, uas muaj lub zog ze ntawm cov hlau alloy tab sis hnyav ib nrab ntawm cov hlau thiab tuaj yeem tiv taus qhov kub siab tshaj 300 degree.
