Raws li ib qho tseem ceeb hauv fasteners, cov txiv ntoo 'ncaj qha cuam tshuam rau kev ntseeg tau, qhov ruaj khov, thiab ib puag ncig kev haum ntawm kev sib txuas. Ceev cov ntaub ntawv sib txawv muaj lawv tus kheej lub zog, corrosion tsis kam, nqi, thiab cov ntawv thov siv tau. Cov khoom siv txiv ntoo muaj xws li hlau, hlau hlau, hlau hlau, tooj liab, thiab tsis- nws cov ntaub ntawv hlau.
1. Carbon Steel Ceev
Carbon Steel txiv ntoo yog qhov muaj feem ntau thiab tus nqi {{} {{{{{2} {{3} {}} carbon steel. Tsawg -} cov txiv ntoo steel (xws li Q235) feem ntau yog galvanized lossis phosphated los txhim kho cov xeb tsis kam thiab yog haum rau kev siv cov tshuab thiab kev siv khoom lag luam. Nruab nrab - Thiab siab}} Tus kab mob thiab kub heev hauv kev siv hluav taws xob, xws li kev siv tsheb ntau dua, xws li kev siv tsheb thiab kev siv tshuab. Txawm li cas los xij, cov roj carbon steel muaj cov tsis zoo corrosion tsis kam thiab yuav tsum muaj kev tiv thaiv ntxiv hauv ib puag ncig vaum lossis xeb.
2. Stainless hlau ceev
Stainless Hlau Ceev, nrog corrosion tsis kam raws li lawv cov txiaj ntsig tseem ceeb, thiab {} {} {} {}} Kev ua kom zoo rau cov chloride corrosion thiab yog haum rau cov tub rog ua lag luam tsis muaj nqi, ua rau muaj cov ntaub ntawv uas tsis muaj zog, ua rau muaj cov ntaub ntawv uas tsis muaj zog Stainless cov txiv ntoo yog feem ntau muaj zog dua cov pa roj carbon hlau muaj zog, tab sis muaj ntau dua qhov muaj kev ruaj khov nyob hauv ib puag ncig hnyav.
3. Alloy Steel Ceev
Alloy Steel neeg rau kev txhim kho lawv cov kev ua tau zoo tag nrho los ntawm kev ntxiv cov ntsiab xws li chromium, npib tsib xee, thiab molybdenum. Lawv feem ntau siv nyob rau hauv high - siv} kev siv lossis siab-}} qhov chaw ib puag ncig. Piv txwv li, 40CR Exceling Steel txiv ntseej, tom qab ua kom sov thiab hnav tsis kam, ua rau lawv muaj kev siv hluav taws xob zoo li xws li cov tshuab tsheb thiab aerospace. Nickel {{{}}} Raws li cov txiv ntoo alonlot (piv txwv li cov khoom siv nyob hauv huab cua (tab sis muaj nqi ntau dua thiab feem ntau siv hauv cov ntawv thov tshwj xeeb.
4. Tooj thiab tooj liab Alloy Ceev
Tooj liab ceev (xws li tooj dag H62) muaj hluav taws xob H62) muaj hluav taws xob zoo thiab thermal ua haujlwm thiab qee qhov℃ntawm corrosion tsis kam. Lawv feem ntau siv hauv cov khoom siv hluav taws xob, cov li qub, lossis cov ntawv thov uas xav tau kev tiv thaiv cuam tshuam. Bronze (Tin Bronze) Ceev, vim lawv cov hnav tsis kam thiab kev sib txhuam cov khoom sib xyaw, yog qhov tsim nyog rau cov ntawv sib txuas hauv nkoj propellers lossis cov tshuab hnyav. Txawm li cas los xij, cov roj coper alloys muaj qis dua lub zog thiab feem ntau siv nyob rau hauv tsis yog {4 4} {{6} torque kev siv.
5. Tsis - nawj txiv ceev
Tsis - cov txiv ntoo (xws li nylon thiab yas) paub txog lawv lub teeb, insulating, thiab corrosion {{1} {tsis tshua muaj zog. Lawv feem ntau pom hauv cov khoom siv hluav taws xob, rooj tog zaum thiab cov xov tooj siv chipelines. Nylon txiv ntoo yog kua qaub - thiab alkali- tiv taus thiab yuav tsis puas controchemical corrosion. Txawm li cas los xij, lawv qhov kub tsis kam (feem ntau tsawg dua lossis sib npaug nrog 120 degree) thiab lub zog txwv lawv daim ntawv thov. Lawv feem ntau siv nyob rau hauv qis {{9} h siab} siab lossis ib ntus kev siv nyiaj ib ntus.
Lub ntsiab
Kev xaiv ntawm cov noob txiv ntoo yuav tsum muaj kev txiav txim siab ntawm cov khoom uas yuav tsum tau ua, ib puag ncig cov cai (xws li corrosion thiab ntsuas kub), raug nqi, thiab cov cai, thiab cov kev xav tau, thiab cov kev xav tau thiab ua haujlwm. Carbon Steel txiv ntoo yog yig thiab siv tau, stainless hlau txiv ntoo yog tsim nyog rau siab muaj siab muaj cov txiaj ntsig zoo hauv cov ntawv thov. Cov ntaub ntawv xaiv kho tau tuaj yeem txhim kho kev ntseeg tau thiab txoj kev pabcuam lub neej ntawm kev ua kom nrawm.
