ASTM A240 ASME SA240 904L duplex steel ntawv phaj
Alloy 904L (UNS N08904, 1.4539) yog austenitic stainless hlau high-alloy austenitic stainless hlau nrog cov ntsiab lus tsis tshua muaj carbon, nws muaj kev tiv thaiv zoo heev hauv ntau qhov chaw xws li dej hiav txwv thiab cov kua qaub. Nws cov ntsiab lus tsis tshua muaj carbon yuav pab txo qis txoj hauv kev ntawm rhiab heev thaum vuam lossis kub kub. Cov khoom zoo tshaj plaws ua rau ASTM A240 904L daim hlau yog cov khoom tseem ceeb rau kev tsim cov tank, kav dej, cov khoom siv hluav taws xob, cov reactors, thiab cov qauv hauv hiav txwv.

A240 904L stainless hlau phaj pom nws cov ntawv thov hauv ntau qhov kev lag luam:
1. Kev lag luam tshuaj lom neeg: Lub phaj yog siv rau cov khoom siv ntau lawm xws li reactors, tanks, heat exchangers, thiab piping systems. Lub siab corrosion kuj ntawm cov phaj no ua rau nws tsim nyog rau kev ua cov tshuaj acidic heev.
2. Kev lag luam roj thiab roj: Cov phaj yog siv rau hauv kev tsim cov roj av offshore platforms, seawater desalination nroj tsuag, thiab cov kav dej. Lub phaj resists chloride-induced kev nyuaj siab corrosion cracking, ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau offshore daim ntaub ntawv.
3. Pharmaceutical kev lag luam: Lub phaj yog siv los ua cov tso tsheb hlau luam thiab cov reactors rau kev tsim cov khoom siv tshuaj. Cov ntsiab lus ntawm cov pa roj carbon tsawg ntawm cov phaj txo qis qhov kev pheej hmoo ntawm kev hnov mob thaum vuam lossis kub kub.
4. Marine kev lag luam: Lub phaj yog tiv taus corrosion nyob rau hauv seawater thiab lwm yam hnyav marine ib puag ncig. Nws yog, yog li ntawd, siv los tsim cov kiv cua shafts, shipbuilding, thiab ntau yam marine lug.
