420 Bir Fidsan oo aan Daxal lahayn
Sharaxaad Gaaban:
Baararka Fidsan ee Din 1.4034 SS 430, Baararka Fidsan ee SS UNS S42000, Baarka Fidsan ee Birta aan Lahayn ee 420, Baararka Qabow ee Birta aan Lahayn ee 420 ee Shiinaha.
Birta aan miridhku lahayn ee heerka 420 waa bir kaarboon sare leh oo leh ugu yaraan chromium content oo ah 12%. Sida birta kale ee aan miridhku lahayn, heerka 420 sidoo kale waa la adkeyn karaa iyada oo loo marayo daaweynta kulaylka. Waxay bixisaa dabacsanaan wanaagsan xaaladdeeda aan miridhku lahayn iyo sifooyin iska caabin ah oo aad u fiican marka birta la safeeyo, la dhulka dhigo ama la adkeeyo. Heerkani wuxuu leeyahay adkaanta ugu sarreysa - 50HRC - dhammaan heerarka birta aan miridhku lahayn ee leh 12% chromium.
