Cov ntsiab lus tseem ceeb hauv 304 yog chromium thiab npib tsib xee, uas muab nws zoo heev corrosion. Nws muaj zoo corrosion tsis kam, yog ducile thiab condile thiab condile, thiab muaj kev weldability zoo. Tus qauv Austenitic tso cai sib sib zog nqus duab yam tsis muaj nyiaj nruab nrab.
Kev txuam ntawm tooj liab mus rau qib 904L alloys ua rau nws tiv taus corrosion, tshwj xeeb tshaj yog cov kua qaub, thiab cov hlau ua kom tiv taus kub.
Hlau tuav & RDSbelongs rau ib tug super ustenitic qib ntawm tsis-stabilized stainless hlau. Stainless hlau 904L yeeb nkab yog tsim nrog kev siv tshuaj lom neeg muaj pes tsawg xyoo 19% rau 23% ntawm chromium nrog 23% ntawm npib tsib caug thiab 4-5% ntawm molybdenum. Cov ntsiab lus muab cov tsis tau no N08904 seamless kav dej tsis kam tiv taus rau corrosive thiab txo cov xov xwm hauv cov chaw sib txawv. Lub ASTM A213 TP904L cov hlab ua haujlwm tau zoo nyob rau hauv kub txog li 400 degrees C uas dilute sulfuric acid yog tam sim no. Cov no 1.4539 cov raj muaj peev xwm tau yooj yim siv nyob rau hauv cov kev mob aqueous thiab tuaj yeem welded nyob rau hauv qhov chaw nram cov txheej txheem kev sib dhos. Lub AISI 904L tubing cov khoom ua kom zoo nkauj thiab muaj peev xwm. Cov 1.4539 cov hlab feem ntau yog cov tshuaj txias ntawm cov txheej txheem kev kho mob thaum kub ntawm 1090 txog 1175 degrees C.
UN tsis muaj N08904 tseem hu ua 904L ntog hauv Austenitic Stainless pawg. ASTM A213 TP904L raj muaj siab molybdenum thiab tsawg heev cov ntsiab lus muaj roj carbon. Cov ntsiab lus tooj liab hauv lub alloy heev txhim kho kom muaj zog reducing muaj zog acids, tshwj xeeb tshaj yog (H2SO4) sulfuric acid. 904L muaj kev tiv taus zoo dua. Ti chloride nres tawm tsam ob qho kev nyuaj siab corrosion tawg thiab crevice \ / pitting corrosion. Nrog zoo weldability thiab formability 904l kuj tswj cov xeev tsis muaj kev sib nqus hauv txhua qhov xwm txheej. 904L muab kev nruj heev, txawm tias kom muaj cryogenic kub nrog nws cov qauv Autrentic. Tus Asme Sb 677 tsis yog n08904 seamless yeeb nkab yog tsim rau kev siv hauv cov kev siv kub siab thiab siab. Lub siab-zog asme sme sb 677 904L kav yog tsim tsis muaj velds lossis nqaws thiab tsim los ntawm cov txheej txheem Extrusion. Qhov no muab cov qauv no 20% ntau dua load-kev muaj peev xwm thaum piv rau cov SS 904L Welded yeeb nkab. Tab sis, ib qho yeeb nkab welded pheej yig dua thiab siv sijhawm ua kom muaj sijhawm. Cov kav dej no yog tsim los ntawm vuam daim ntawv los yog sawb nyob rau hauv qhov chaw nram qab no cov qauv vuam cov txheej txheem.
Molybdenum nyob rau hauv Incoloy 925 plam ntawm Flanges AIDS tsis kam rau pitting thiab crevice corrosion whilst chromium muaj kev tawm tsam rau oxidizing ib puag ncig.
