Hlau Stainless 904 / 904L

Khoom Nthuav dav

Cov Npe Pauv Hloov Npe: Alloy 904L, N08904, W.Nr 1.4539, N08904, Cr20Ni25Mo4.5Cu

904L yog Super Austenstic Stainless Hlau nrog cov pa roj carbon tsawg cov ntsiab lus. Qib yog npaj rau siv nyob rau hauv muaj mob hnyav tsis muaj mob. Nws tau raug thov ua pov thawj ntau xyoo thiab tau pib tsim los kom tiv taus corrosion hauv dilute sulfuric acid. Nws yog qhov qauv thiab pom zoo rau kev siv lub nkoj siab hauv ntau lub tebchaws. Kev teeb tsa, 904L yog qhov zoo tshaj plaws austenitic thiab tsis tshua nkag siab cov nag lossis daus ferrite thiab sigma theem tshaj cov qib austenitic nrog cov ntsiab lus siab molybdenum. Tus yam ntxwv, vim muaj kev sib xyaw ntawm cov ntsiab lus tseem ceeb ntawm chromium, npib tsib xee, molybdenum thiab tooj liab 904L tau muaj qhov tsis kam tiv thaiv zoo rau kev xeb, tshwj xeeb hauv sulfuric thiab phosphoric.

Vim li cas Alloy 904L?

Kev tawm tsam zoo rau pitting corrosion thiab kev ua haujlwm tsis xeb

Muaj peev xwm tiv thaiv kev ntxhov siab corrosion cracking, intergranular, zoo machinability thiab weldability

Hauv txhua txhua yam ntawm phosphates904L alloy corrosion tsis kam zoo dua li cov hlau tsis muaj zog.

Hauv kev muaj zog oxidizing nitric acid, piv rau siab loj tsis muaj molybdenum qib steel, 904Lshows qis dua corrosion tsis kam.

Cov alloy no muaj cov xeb tiv thaiv tau zoo dua li cov hlau loj.

Txo qhov kev hloov kho xeb ntawm lub qhov thiab qhov khoob rau cov ntsiab lus siab ntawm nickel, thiab muaj qhov zoo tiv thaiv kev ntxhov siab corrosion ua kom tawg, hauv ib puag ncig ntawm cov tshuaj chloride, kev saib xyuas cov tshuaj hydroxide thiab cov nplua nuj hydrogen sulphide.

Alloy 904L Thov teb :

Cov cuab yeej siv roj thiab petrochemical , xws li reactor ntawm cov cuab yeej siv roj, thiab lwm yam.

Sulfuric acid cia thiab thauj cov khoom thauj, xws li cov cua sov hloov, thiab lwm yam.

Lub zog hluav taws xob flue roj desulfurization devicen, Qhov tseem ceeb ntawm kev siv: lub nqus ntauwd lub cev, flue, sab hauv seem, txau system, thiab lwm yam

Organic acid siv cov nplauv thiab kiv cua hauv cov txheej txheem tsim.

Cov tshuaj tua dej cog, cov cua kub tawm, cov khoom siv papermaking, sulfuric acid, cov khoom siv nitric acid, kua qaub,

Kev lag luam kws kho mob thiab lwm yam cuab yeej siv tshuaj, lub nkoj siab, khoom noj khoom haus.

Tshuaj: centrifuge, reactor, thiab lwm yam.

Cov khoom noj cog: lub lauj kaub ua kua ntses, cawv txiv hmab, ntsev, khoom siv thiab hnav khaub ncaws.

Txhawm rau sulfuric acid muaj zog corrosive nruab nrab hlau 904 l yog txuam.
