Horumar la taaban karo,904L birta aan birta lahaynWaxay u soo baxeen inay yihiin walxaha la jecel yahay ee warshadaha heerkulku sarreeyo, iyagoo ka beddelaya habka qaybaha kala duwani ay u maareeyaan jawiga kulaylka ba'an. Iyada oo iska caabbinta kulaylka gaarka ah iyo adkeysiga daxalka, 904L birta aan daxalka lahayn ayaa iskeed isu taagtay sidii ikhtiyaarka ikhtiyaarka ah ee codsiyada muhiimka ah halkaasoo heerkul sare uu caqabad ku yahay.
Rafcaanka 904L birta aan-ka-soo-baxa lahayn waxay ku jirtaa hal-abuurkeeda gaarka ah iyo sifooyinka. Daawahaani waxa ay ku faantaa koomiyad sareeysa oo ah 23-28%, oo ay weheliso kaarboon yar iyo maaddo nikkel sare ah (19-23%). Tilmaamahani waxay gacan ka geystaan awoodda cajiibka ah ee lagu ilaalinayo sharafta qaabdhismeedka iyo iska caabinta oksaydhka xitaa xaaladaha sida caadiga ah u keeni kara hoos u dhac weyn oo ku yimaada alaabta kale.
