Dab tsi stainless hlau yog 1.4571 sib npaug?
1.4571Nws yog sib npaug rau cov hlau stainlessAISI 316TICov. Ob qho kev tsim qauv xa mus rau tib yam Anustenitic Stainless Stretized nrog titanium, ua1.4571Lub chaw nyob sab Europe (en) thiab316TiMiskas tsim qauv (AISI). Nws yog cov kev ua tau zoo ntawm cov khoom siv hlau uas paub txog nws qhov zoo heev corrosion tsis kam thiab muaj kev ruaj khov nyob ntawm qhov kub siab, ua rau nws haum rau cov ntawv thov.

Corrosion Kuj
Tus hlauEn 1.4571Nws yog tiv taus ntau duaEn 1.4301 (x5crni18-10)thiab1.4401 (x5cnimo17-12-2)Cov. Vim tias nws muaj Titanium thiab cov foosTICNrog carbon, ntau txo qhov kev pheej hmoo ntawm cov rhiab vim yog cov xeb hauv nruab nrab. Txawm li cas los xij, ntawm cov kub thiab hauv kub siab nitric acid, chlorides, lossis alkaline daws teeb meem, tseem ceeb corrosion, tseem ceeb corrosion muaj peev xwm tshwm sim.
Hwj txwv
Tus hlauEn 1.4571Nws muaj qhov zoo weldability, tsis tas yuav preheating ua ntej vuam, thiab feem ntau tsis xav tau kev kho cua sov tom qab vuam.
