Horumar muhiim ah,Baararka birta aan daxalka lahayn ee 904Lwaxay soo baxeen iyagoo ah walxaha ugu wanaagsan warshadaha heerkulka sare, taasoo kacaan ku ah habka qaybaha kala duwan ay ula macaamilaan jawiga kulaylka daran. Iyada oo leh iska caabbinta kulaylka ee gaarka ah iyo adkeysiga daxalka, birta aan miridhku lahayn ee 904L ayaa isu beddeshay inay tahay ikhtiyaarka ugu habboon ee loogu talagalay codsiyada muhiimka ah halkaas oo heerkulka sare uu caqabad ku yahay.
Soo jiidashada birta aan miridhku lahayn ee 904L waxay ku jirtaa qaab-dhismeedkeeda iyo sifooyinkeeda gaarka ah. Dahaarkani wuxuu ku faanaa chromium oo sarreeya oo ah 23-28%, oo ay weheliso kaarboon yar iyo nikkel oo sarreeya (19-23%). Astaamahani waxay gacan ka geystaan awooddeeda cajiibka ah ee lagu ilaalinayo sharafta qaab-dhismeedka iyo iska caabbinta oksaydhka xitaa xaaladaha caadiyan sababi lahaa hoos u dhac weyn oo ku yimaada agabka kale.
