AISI 440B EN 1.4112 Silig bir ah oo qabow la jiido
Sharaxaad Gaaban:
440B birta aan lahayn waa nooc ka mid ah birta aan lahayn martensitic oo ka kooban chromium, carbon, iyo walxo kale. Waxaa inta badan loo isticmaalaa codsiyo kala duwan ay sabab u tahay iska caabin daxalka, engegnaantooda wanaagsan, iyo qiimo jaban marka la barbar dhigo qaar ka mid ah darajooyinka kale ee ahama.
