FAQ:
Q1: Dab tsi yog qhov txawv ntawm Nickel Alloy 20 lub caij nplooj ntoos hlav xauv lub tshuab ntxhua khaub ncaws thiab 316L lossis 2205?
A: Qhov txawv yog nyob rau hauv lawv cov corrosion kuj. Alloy 20 yog tsim tshwj xeeb los tiv thaiv ib puag ncig nyuaj uas cuam tshuam nrog sulfuric acid, phosphoric acid, thiab chloride ions. 316L thiab 2205 cov ntaub ntawv tsis ua haujlwm zoo hauv qhov chaw zoo li no.
Q2: Qhov ntsuas kub npaum li cas rau Alloy 20 lub caij nplooj ntoos hlav ntxhua khaub ncaws?
A: Lawv tuaj yeem siv tau zoo rau lub sijhawm ntev hauv qhov kub ntawm -200℃txog 550 degree; Lawv pom zoo heev toughness nyob rau hauv qis kub thiab ruaj khov elasticity ntawm kub kub.
Q3: Yuav ua li cas ro xaiv ntawm DIN 127A thiab DIN 127B ntawm Alloy 20 caij nplooj ntoos hlav ntxhua khaub ncaws?
A: Hom A (Standard) yog qhov tsim nyog rau qis - mus rau - cov ntawv thov siab nruab nrab thiab cov xwm txheej cuam tshuam nrog kev vibration niaj hnub. Hom B (Havy-Lub Luag Haujlwm) muaj qhov tuab tuab dua - ntu thiab muaj zog elasticity, ua rau nws haum rau siab -siab thiab siab - vibration ib puag ncig uas yuav tsum tau muaj zog xauv ntau dua.
Q4: Alloy 20 washers puas tuaj yeem siv ua ke nrog carbon steel lossis stainless hlau bolts?
A: Nws tsis pom zoo, vim qhov no tsim kev pheej hmoo ntawm galvanic corrosion.
Q5: Nyob rau hauv ib puag ncig sulfuric acid, yog Alloy 20 washers superior rau Monel 400 washers?
A: Rau ib puag ncig sulfuric acid, Alloy 20 yog qhov kev xaiv zoo tshaj. Thaum Monel 400 muaj kev tiv thaiv ntau dua rau dej hiav txwv thiab hydrofluoric acid, nws cov corrosion kuj nyob rau hauv kub sulfuric acid yog qis dua li ntawm Alloy 20.
Q6: Cov ntaub ntawv dab tsi yuav tsum tau txiav txim rau kev cai, tsis yog -tus qauv Alloy 20 lub caij nplooj ntoos hlav ntxhua khaub ncaws?
A: Koj yuav tsum muab qhov ntev (ntev txoj kab uas hla, sab nraud, thiab tuab), cov qauv siv tau (DIN / ASME), hom (Hom A lossis B), kom muaj nuj nqis, thiab kev npaj ua haujlwm.
Q7: Alloy 20 lub caij nplooj ntoos hlav ntxhua khaub ncaws puas tuaj yeem siv rau hauv cov dej hiav txwv thiab cov tshuaj chloride sib xyaw ua ke - thaj chaw nplua nuj?
A: Yog lawm. Lawv ua tau zoo heev tiv thaiv chloride-induced stress corrosion cracking (SCC)-kev ua tau zoo uas deb tshaj li ntawm 316L.
