C45 steel bar - din 17220 EN10083
  • I guess everyone know that C45/1045 is the base steel,it’s nothing special,and also the the chemistry is not complex，In China,it’s not a hard working to control chemicalcomponent .
  • But once C45 involve about the physical properties,that is another issue,such as Tensile strength,Yield strength,Elongation,that is about the heat treatment issue.and make sure the hardness is meet customer’s demand.

Moreover,once the C45/1045 diameter over 350mm,you really need to more careful about the quality,there might some blow hole or crack problem,of course ,if you have higher demand,you will also check microstructure.
