Khoom siv DIN 1.4539 Aisi 904l X1NiCrMoCu25-20-5 Stainless hlau
Khoom Description
904L super austenitic stainless hlau (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN1.4539) yog cov pa roj carbon tsawg, siab-alloy austenitic stainless hlau tsim tshwj xeeb rau cov mob hnyav corrosion. Nws muaj kev tiv thaiv corrosion zoo heev hauv dilute sulfuric acid thiab nta cov ntsiab lus siab chromium, cov ntsiab lus nickel txaus, thiab ntxiv tooj liab rau cov kua qaub muaj zog. Nws qhia tau hais tias tshwj xeeb tsis kam rau chloride pitting thiab kev ntxhov siab corrosion tawg nrog kev puas tsuaj tsawg lossis tawg. Tsis tas li ntawd, nws muaj superior machinability thiab weldability, ua rau nws haum rau siab hlab ntsha.

Corrosion kuj ntawm 904L / DIN 1.4539 / X1NiCrMoCu25-20-5 stainless hlau:
Vim muaj cov ntsiab lus carbon tsawg ntawm 904L/DIN 1.4539/X1NiCrMoCu25-20-5 (siab tshaj 0.020%), yuav tsis muaj carbide nag lossis daus nyob rau hauv kev kho cua sov thiab vuam tej yam kev mob. Qhov no tshem tawm qhov kev pheej hmoo ntawm intergranular corrosion uas tshwm sim tom qab kev kho cua sov thiab vuam. Vim nws cov ntsiab lus siab chromium nickel molybdenum thiab qhov sib ntxiv ntawm tooj liab, 904L tuaj yeem passivated txawm nyob rau hauv kev txo qis ib puag ncig xws li sulfuric acid thiab formic acid.
Cov ntsiab lus npib tsib xee siab ua rau qis dua corrosion txawm tias nyob hauv lub xeev nquag. Nyob rau hauv ntshiab sulfuric acid nrog ib tug concentration ntau ntawm 0-98%, kev siv kub ntawm 904L tuaj yeem ncav cuag 40 degrees Celsius. Nyob rau hauv ntshiab phosphoric acid nrog ib tug concentration ntau ntawm 0-85%, nws corrosion kuj zoo heev.
Cov impurities muaj kev cuam tshuam rau corrosion kuj ntawm industrial phosphoric acid uas ua los ntawm cov txheej txheem ntub dej. Ntawm txhua hom phosphoric acid, 904L / DIN 1.4539 / X1NiCrMoCu25-20-5 muaj kev tiv thaiv corrosion zoo dua li cov hlau tsis huv. Nyob rau hauv oxidizing nitric acid heev, 904L muaj qis corrosion kuj piv rau high alloyed steel qib yam tsis muaj molybdenum.
Hauv hydrochloric acid, kev siv 904L tsuas yog txo qis ntawm 1-2%. Nyob rau hauv cov ntaub ntawv no concentration. Lub corrosion kuj ntawm 904L yog zoo dua li cov pa stainless hlau. 904L / DIN 1.4539 / X1NiCrMoCu25-20-5 steel muaj siab ua haujlwm rau pitting corrosion.
Nws tsis kam mus rau crevice corrosion kuj zoo heev hauv cov tshuaj chloride. Cov ntsiab lus npib tsib xee siab ntawm 904L (DIN 1.4539 / X1NiCrMoCu25-20-5) txo qis tus nqi corrosion hauv pits thiab crevices. Ordinary austenitic stainless hlau tej zaum yuav rhiab heev rau kev ntxhov siab corrosion nyob rau hauv ib puag ncig nplua nuj nyob rau hauv chloride ntawm qhov kub siab tshaj 60 degrees Celsius. Los ntawm kev nce cov ntsiab lus npib tsib xee ntawm cov hlau tsis huv, qhov kev xav tau no tuaj yeem txo qis. Vim nws cov ntsiab lus npib tsib xee siab, 904L nthuav tawm qhov ua haujlwm siab rau kev ntxhov siab corrosion tawg hauv cov tshuaj chloride, cov ntsiab lus hydroxide cov ntsiab lus, thiab ib puag ncig nplua nuj hauv hydrogen sulfide.
