Kev txiav txim siab yog tias cov txiv ntoo cov khoom ua tau raws li qhov yuav tsum tau ua kom paub tseeb los ntawm cov txheej txheem xws li kev txheeb xyuas daim ntawv lo, spectral tsom xam, kev kuaj hlau nplaum, kuaj tawv, thiab daim ntawv pov thawj los xyuas kom meej tias nws cov tshuaj muaj pes tsawg leeg, cov khoom siv kho mob, thiab kev siv ib puag ncig zoo sib xws.
1. Txheeb xyuas cov ntawv cim khoom thiab cov qhab nia raws cai cov txiv ntoo feem ntau muaj cov khoom siv lossis cov qhab nia muaj zog luam tawm ntawm lawv qhov chaw:
Stainless hlau txiv ntseej: Cov cim feem ntau suav nrog "A2-70" thiab "A4-80," qhov "A2" sawv cev rau 304 stainless hlau, "A4" sawv cev rau 316 stainless hlau, thiab "70" qhia tias lub zog tensile tsawg kawg yog 700 MPa.
Carbon Steel Nuts: Cim nrog qib xws li "8.8" thiab "10.9," qhov twg cov lej sawv cev rau lub zog tensile nominal (MPa / 100) thiab yield zog piv (× 10), feem. Cov khoom siv tuaj yeem raug xam los ntawm cov cim.
2. Kev txiav txim siab yam khoom ua ntej ntawm kev kuaj hlau nplaum
Siv cov hlau nplaum ze ntawm cov txiv ntoo rau kev sim yooj yim:
Tsis yog- sib nqus los yog tsis muaj zog sib nqus: Feem ntau austenitic stainless hlau xws li 304 lossis 316;
Cov hlau nplaum tseem ceeb: Tej zaum yuav yog 410 martensitic stainless hlau lossis carbon hlau, tsis haum rau kev siv siab corrosion.
