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

By Materials & Welding
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!

Hi











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

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

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
