AISI 440B EN 1.4112 Silig Bir ah oo Qabow La Soo Dhigay
Sharaxaad Gaaban:
Birta aan miridhku lahayn ee 440B waa nooc ka mid ah birta aan miridhku lahayn ee martensitic oo ka kooban chromium, kaarboon, iyo walxo kale. Badanaa waxaa loo isticmaalaa codsiyo kala duwan sababtoo ah iska caabbinta daxalka, adkaanta wanaagsan, iyo kharash yar marka la barbar dhigo heerarka kale ee birta aan miridhku lahayn.
