1. Nyob rau hauv cov huab cua zoo tib yam (nyob deb nroog / nroog)
qw 550n: Cov ntaub ntawv ruaj khov patina, corrosion yog qeeb thiab siv tau rau ntau xyoo.
Stainless hlau (304/316): Yuav luag tsis muaj xeb, nto tseem ci thiab huv si.
Kev tshwm sim: Stainless hlau tseem zoo dua, tab sis Q550NH tuaj yeem ua tau raws li cov kev xav tau yooj yim.
2. Nyob rau hauv industrial / acid nag ib puag ncig
qw 550n: Patina yog eroded, corrosion accelerates.
304 stainless hlau: Zoo corrosion kuj.
316 stainless hlau: Zoo heev, yuav luag tsis cuam tshuam.
Kev tshwm sim: Stainless hlau yog qhov zoo dua.
3. Nyob rau hauv ntug dej hiav txwv / ntsev-nplua ib puag ncig
qw 550n: Patina tsis ua haujlwm, xeb sai thiab tsis sib xws.
304: Tej zaum yuav muaj me ntsis pitting.
316: ruaj khov heev, muaj zog chloride kuj.
Kev tshwm sim: Stainless hlau yog qhov zoo tshaj plaws.
4. Nyob rau hauv high humidity, qhov cua tsis zoo, damp lub sij hawm ntev
qw 550n: Tsis tuaj yeem tsim patina tiv thaiv, ua kom xeb.
Stainless hlau: Tseem tiv taus heev.
Kev tshwm sim: Stainless hlau zoo dua.
5. Nyob rau hauv dej immersion / faus ib puag ncig
qw 550n: Corrodes sai, zoo ib yam li cov hlau zoo tib yam.
Stainless hlau: Tswj kev ua haujlwm zoo heev.
Kev tshwm sim: Stainless hlau yog qhov tseem ceeb.
6. Nyob rau hauv siab -kub ib puag ncig
qw 550n: Loses patina, cov ntaub ntawv xoob oxide nplai.
Stainless hlau: Ua kom zoo oxidation tsis kam.
Kev tshwm sim: Stainless hlau zoo dua.
