Kev sib piv ntawm 1.4306 thiab 1.4571 stainless hlau
Tso lus
Hauv kev xaiv xaiv teb, sib piv ntawm1.4306thiab1.4571Stainless hlau tseem yog ib lub ntsiab lus kub. Tus qub yog EU qib ntawm tus nqi-ua tau zoo304, thaum lub tom kawg yog qhov hloov kho tshiab ntawm316Ti, muaj titanium thiab molybdenum rau kev txhim kho corrosion tsis kam. Ob qho tib si yog Austenitic stainless hlau, tab sis lawv qhia qhov sib txawv ntawm cov peev xwm tseem ceeb xws lichloride corrosion tsis kam, Kev Kub Siab Lub Zog, thiabhwj txwvCov. Kab lus no muab ib qho kev ntsuas kom tob tob los ntawmTshuaj Muaj TshuajthiabKev ua haujlwm tsis sib haumrauCov Ntawv Thov Siv, pab koj txiav txim sai cov khoom uas tau tsim nyog rau koj cov xwm txheej tshwj xeeb, thiab zam cov khoom lag luam tsis ua haujlwm los ntawm cov khoom xaiv tsis raug.

1.430 thiab 1.4571 stainless hlau corrosion tsis kam
1.4306 (304L):
Muaj cov kev tiv thaiv zoo heev rau ib puag ncig corrosive me, xws li dej, ua zaub mov, thiab cov ntawv thov sab hauv. Txawm li cas los xij, nws tsis tshua muaj kev tiv thaiv mus rau chloride-ntxias pitting corrosion thiab kev nyuaj siab corrosion tawg thaum raug cov tshuaj muaj ntshav lossis ib puag ncig.
1.4571 (316Ti):
Txhim kho corrosion tsis kam vim molybdenum cov ntsiab lus thiab titanium ntxiv, uas pab tiv thaiv kom tsis txhob muaj kev sib txuam ntawm kev kub siab dua. Qhov zoo tshaj plaws rau cov chaw ua haujlwm marine, siv tshuaj lom neeg, thiab cov tshuaj chloride ntau, ua rau nws haum rau cov tubrog nkoj thiab cov ntawv thov tawm.
