1. Kev Sib Tw Ua Ntej Raws li Kev Pom Zoo thiab Cov Khoom Sib Nqus: Cov roj carbon steel / hlau cov txiv ntseej feem ntau muaj zog sib nqus thiab tuaj yeem ua galvanized lossis blackened. 304/316 stainless hlau yuav luag tsis yog- hlau nplaum nyob rau hauv ib txwm muaj, tab sis tej zaum yuav muaj zog hlau nplaum tom qab ua haujlwm txias. Cov txiv ntseej tooj liab yog cov xim daj/ntsuab-liab, thaum cov txiv ntseej txhuas yog sib dua thiab xim dawb.
2. Precise Testing with Professional Instruments: Direct- nyeem spectrometers tuaj yeem ncaj qha txheeb xyuas cov tshuaj muaj pes tsawg leeg ntawm cov hlau, kom paub qhov txawv ntawm cov qib stainless hlau xws li 201, 304, thiab 316. Ua ke nrog Rockwell hardness kuaj, nws tuaj yeem sib txawv ntawm cov pa roj carbon zoo tib yam 5} hlau.
3. Kev Tshawb Fawb Txog Kev Tshawb Fawb: Kev kuaj ntsev ntsev tuaj yeem txheeb xyuas cov khoom siv xeb thiab xeb. Cov khoom lag luam cov ntaub ntawv tshaj tawm kuj tuaj yeem raug kuaj xyuas cov qhab nia ua tau zoo sib xws kom paub meej tias kev ua raws cai.
