Halayen bakin karfe 304
The Properties na 304 bakin karfe lebur karfe ne low thermal watsin, game da 1/3 na carbon karfe, resistivity game da 5 sau na carbon karfe, mikakke fadada coefficient game da 50% fiye da carbon karfe, da yawa girma fiye da carbon karfe. Bakin karfe na walda sanduna gabaɗaya sun kasu kashi biyu: nau'in calcium titanium acidic da nau'in ƙarancin hydrogen na alkaline. Ƙananan sandunan walda na bakin karfe na hydrogen suna da mafi girman juriya na thermal, amma samar da su bai kai irin sandunan walda na calcium titanium ba, kuma juriyar lalata su ma ba ta da kyau. Calcium titanium irin bakin karfe walda sanduna suna da kyakkyawan tsarin aiki kuma ana amfani da su fiye da samarwa. Tun da bakin karfe yana da halaye da yawa daban-daban daga carbon karfe, ta walda tsari bayani dalla-dalla kuma daban-daban daga carbon karfe. Bakin karfe gratings suna da ɗan ƙaramin mataki na kamewa, kuma ana yin su da dumama da sanyaya a cikin gida yayin walda, wanda ke haifar da dumama da sanyaya mara kyau, kuma walda zai haifar da damuwa da damuwa mara daidaituwa.
