Re: [MW:10793] Impact testing temp. for EN19 steel

Izod can be done on steels also but technically, Charpy is more accurate; as there are some issues when doing at lower temperatures. This is due to the reason that specimen has to be fixed on the holder everytime, and it is subjected to impact only on one side of the notch.

Experts may please correct, if i am wrong.

Manpeet,

 

Izod is for plastics, charpy V notch ductility tesying is common on steels.

Hello !

 

Please can someone answer my general query>

 

Why only Charpy V Notch Testing is mostly used for Impact Testing & why Izod is not  popular.

 

Please give detailed information to understand process thoroughly.

 

Waiting for replies!

Hi

 

Izod will be done at Room temp.,  Unless  otherwise specifically mentioned by spec.

 

Thanks & Regards,

Dear Friends

I wanted to use EN 19 plate in one of my present project, wherein the application demands severe impact loads at room temperature.

I had browsed through the properties of EN 19 plate in various literatures wherein the Izod test values are mentioned @ 55J.

However the Izod testing temperature is not mentioned.

Can anyone help me out or guide me where to refer, so that i can know the Izod testing temperature of this EN 19 steel.

Secondly i would also like to know which of the two will have more toughness and why - EN 19 casting OR EN19 plate ?
The reason being the final component will have to be casted due geometrical complications.


Regards
