Yuav ua li cas txheeb tau 904L stainless hlau los ntawm cov qauv txheem?
Tso lus
904L Stainless HlauYog lub siab-alloy, corrosion-resistant cov khoom siv dav siv nyob rau hauv cov tubrog nkoj, tshuaj lom neeg, thiab tshuaj lag luam. Vim nws cov ntsiab lus npib tsib thiab molybdenum cov ntsiab lus, nws yog feem ntau raug xaiv ntau dua 316L rau kev thov ib puag ncig. Txawm li cas los xij, kom ntseeg tau cov khoom raug yog xaiv lossis tshawb xyuas qhov tseeb, nkag siab txog kev txheeb xyuas qhov twg904L los ntawm cov lej cim thiab cov lus qhia tshwj xeebyog qhov tseem ceeb.

Tswv yim:Qhov kev lees paub thoob plaws ntiaj teb rau 904L yogUnrical n08904, siv thoob daim ntawv pov thawj thiab MTCS (zeb daim ntawv pov thawj).
Yuav ua li cas txheeb tau 904L hauv kev ua tiav lossis kev tshuaj xyuas zoo?
1. Kuaj Kev Ntsuas Mill Xeem Ntawv (MTC)
Saib rau ntawm N08904, 1.4539, lossis x1nicrmocu {{}}} hauv cov khoom siv tshwj xeeb.
Xyuas kom meej tshuaj tshuaj muaj yees ua tau raws li:
Ni: 23–28%
CR: 19–23%
Mo: 4–5%
CU: ~1.5%
Txheeb xyuas raws liASTM B625, ASTM B673, lossisASTM B649Nyob ntawm daim ntawv foos.
2. Cov Khoom Siv Hluav Taws Xob lossis Laser Npav
Cov kav dej, daim hlau, thiab cov kab yuav muaj cim xws li:
"904L \/ n08904 \/ ASTM B625 \/ Thaum Tshav Kub Tsis."
"Rau 1.4539 \/ batch code \/ loj"
Qee lub mills yuav kos ob qho tib siTsis yog thiab en coderau thoob ntiaj teb traceability.
3. Siv lub chaw ntsuas hluav taws xob portable (PMI kuaj)
Kev txheeb xyuas cov khoom (PMI) tuaj yeem tshawb pom cov qib siab tam sim no, MO, thiab qhov txawv ntawm 904L los ntawm 316L los ntawm 316L thiab 317L uas muaj qis alloy.
