Tinjauan Karbon Steel C45 Bar
Baja C45 Babak Bar mangrupa baja karbon sedeng unalloyed, nu oge baja rékayasa karbon umum. C45 mangrupakeun baja kakuatan sedeng jeung machinability alus sarta sipat tensile alus teuing. C45 buleud baja umumna disadiakeun dina hideung panas digulung atawa aya kalana dina kaayaan dinormalisasi, kalawan rentang kakuatan tensile has 570 - 700 Mpa sarta Brinell karasa rentang 170 - 210 boh kaayaan. Sanajan kitu, eta teu ngabales satisfactorily mun nitriding alatan kurangna elemen alloying merenah.
C45 babak baja bar sarua jeung EN8 atanapi 080M40. Baja C45 bar atanapi piring cocog pikeun pabrik bagian sapertos gears, bolts, axles umum-Tujuan jeung shafts, kenop na studs.
