Re: RE: [MW:10846] Impact testing temp. for EN19 steel

Hi Prem,

 

Do u comparing the CVN at what temp. ?

 

After the casting , will undergo any Heat treatment ?

 

To be frank, answer to your question need an R&D to come up with howmuch value will differ.

 

Different types of casting, and will get the different grain sizes/Morphology,Product geometry, may undergo different types of Heat treatment after casting which all govern the CVN/Other properties.

 

I agree that, the general understanding that, Plate have more toughness than casting.

 

Thanks & Regards,

 

K. Babu

Hi Babu

Thanks for your reply.
However my second query is unadressed.

"Secondly i would also like to know which of the two will have more toughness and why - EN 19 casting OR EN19 plate ?"

I feel that plate will have more toughness than casting, but how much ???

Can anyone reply to this please ??

Regards

Prem Nautiyal

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!

testing temp. for EN19 steel









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
