Hardfacing VuamHluav taws xob
Txheem: DIN 8555 (E9-UM-250-KR)
Qauv TSIS MUAJ: TY-C65
Specification & Daim Ntawv Thov:
· Cov electrode tshwj xeeb nrog kev pom kev vuam thiab cov khoom siv kho tshuab.
· Austenite- Ferrites vuam hlau.High lub zog muaj nuj nqis thiab siab tawg kuj.
· Tshwj xeeb tshaj yog haum rau kev koom tes ntawm hardly weldable steels, thaum xav tau siab tshaj plaws ntawm lub vuam seam yog ua.
· Kev ua haujlwm siab tawg thaum koom nrog niam txiv cov hlau uas nyuaj weldability, xws li austenitic thiab ferritic steels, high-manganese steels nrog alloyed thiab non-alloyed steels, tshav kub-kho thiab cov cuab yeej steels.Kev siv hauv kev kho thiab tu lub tshuab thiab tsav cov khoom siv nrog rau hauv kev kho cov cuab yeej.
· Raws li cushion txheej ntawm cov ntaub ntawv no kuj zoo tagnrho suited.
