1.0503, S45C, G10450, AISI 1045
Tilmaamaha Guud
1045/C45 birta waxaa lagu qeexaa inay tahay birta kaarboon dhexdhexaad ah oo leh 0.4% -0.5% Carbon. Waxay bixisaa alxanka wanaagsan, machinability wanaagsan, xoog sare iyo guryaha saamaynta, laakiin hoose ee adkeysi sababtoo ah la'aanta walxo alloying ku haboon.

Sharaxaada C45 waa bir kaarboon dhexdhexaad ah oo la isticmaalo marka la rabo xoog iyo engegnaan ka weyn xaalada "sida duuban" Saxnaanta cabbirka aadka u daran, toosnaanta iyo xoogga saarista ayaa la isku daraa si loo yareeyo xirashada codsiyada xawaaraha sare. La rogmaday, dhulka oo la simay.
