430 stainless hlau pob zoo precision

Q: Kuv yuav xaiv lub hom stainless hlau tsim nyog (304 (L) / 316 (L) / 420 (C) / 440 (C))?Dab tsi yog qhov txawv ntawm 300 thiab 400 series stainless hlau pob?
A: Txhawm rau xaiv cov khoom lag luam hlau zoo rau cov khoom tsis muaj steel hlau, peb yuav tsum paub zoo txog cov khoom ntawm txhua hom thiab daim ntawv thov ntawm cov khoom.Feem ntau siv stainless hlau pob tuaj yeem muab faib ua ob pawg: 300 series thiab 400 series.
300 series "austenitic" stainless hlau npas muaj ntau cov chromium thiab npib tsib xee thiab yog cov theoretically tsis-sib nqus (qhov tseeb yog cov hlau nplaum tsawg heev. Tsis yog-sib nqus yuav tsum tau kho cua sov ntxiv.).Feem ntau lawv raug tsim tsis muaj txheej txheem kho cua sov.Lawv muaj kev tiv thaiv corrosion zoo dua li 400 series (qhov tseeb, qhov siab tshaj plaws corrosion kuj ntawm cov stainless pawg. Txawm hais tias 300 series pob yog tag nrho cov resistant, txawm li cas los xij 316 thiab 304 pob qhia sib txawv rau qee yam khoom. Yog xav paub ntxiv, thov mus saib nplooj ntawv ntawm txawv stainless hlau pob).Lawv tsis nkig tsawg, yog li tuaj yeem siv rau kev siv sealing.400 series stainless hlau pob muaj ntau cov pa roj carbon ntau, uas ua rau nws sib nqus thiab ntau hardness.Lawv tuaj yeem kho tau yooj yim thaum tshav kub kub xws li chrome steel npas lossis carbon steel pob kom nce hardness.400 series stainless hlau pob yog feem ntau siv rau cov ntawv thov uas xav tau dej-ua haujlwm, lub zog, hardness thiab hnav tsis kam.
