Thaum sib piv1.4432nrog1.4571Nyob rau hauv stainless hlau raj, lo lus nug tseem ceeb rau cov neeg yuav khoom tsis yog txhua yam tsis kam, tab sis covkev thov kom haum. Txawm hais tias ob qib muaj nyob rau tsev neeg ntawm austenitic molybdenum stainless hlau, lawv cov kev siv pom tau zoo sib txawv.
Phau ntawv qhia no piav qhia txog kev siv cov raj stainless hlau1.4432thiab1.4571, pab kev yuav cov kws tshaj lij xaiv cov khoom siv raj tsim nyog raws li kev xeb, kub thiab kev pabcuam.
Qhov twg tuaj yeem siv 1.4432 stainless hlau raj?cov
stainless hlau tubes1.4432 (X2CrNiMo17-12-3)Lawv feem ntau siv nyob rau hauv ib puag ncig corrosive heev, xws li tshuaj lom neeg, marine thiab ntawv kev lag luam, vim lawvsuperior tsis kam rau chloride-induced pitting corrosion, siab tshaj li ntawm 316L. Lawv yog cov zoo tagnrho rau cov khoom siv hluav taws xob, cov kav dej, cov tso tsheb hlau luam, cov khoom siv tshuaj thiab cov khoom siv ua zaub mov.
Dab tsi yog daim ntawv thov ntawm 1.4571 stainless hlau raj?cov
stainless hlau tubes1.4571 (AISI 316 Ti)Lawv yog siv nyob rau hauv high corrosion, kub thiab vuam ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj, petrochemical, zaub mov ua, tshuaj thiab shipbuilding industries. Lawv yog cov zoo tagnrho rau cov txheej txheem kab, tshav kub exchangers thiab tso pa system, ua tsaug rau lawv siab molybdenum cov ntsiab lus thiab stabilization nrog titanium.
Dab tsi yog 1.4571 stainless hlau sib npaug?cov
Nws1.4571(X6CrNiMoTi17-12-2) feem ntau sib npaug rauAISI 316 Ti (UNS S31635). Nws yog titanium-stabilized version ntawm 316 austenitic stainless hlau nrog molybdenum, dav siv nyob rau hauv cov teb chaws Europe (EN txuj) rau nws zoo heev corrosion kuj thiab kub stability; Nws qhov sib npaug Japanese (JIS) yogSUS 316 Ti.
