WD-M3 Bokaholimo bo boreleli
Bokaholimo bo Boreleli
Poleiti ea ho Koahela Carbide ea Chromium
MOLEMO:
* Boreleli bo boreleli, sekoahelo se le seng sa ho feta, Ha ho na lifaha tsa ho weld holim'a metsi
* Sebopeho se tsitsitseng sa microstructure le ho thatafala ho fihlela moleng oa ho kopanya
* Khohlano e tlase e sebetsa hantle
* Thepa e ntle haholo ea ho khohlela le ho hanyetsa tšusumetso
* Mocheso o sebetsang <600℃
* Boikhethelo ka sekoahelo se ikhethang se seng sa makenete
* E fumaneha ka leloala le qetellong ea bokaholimo bo bentšitsoeng esale pele
