lamiere hardox

[Swarzy]

Bye to all,

I need information. for the design of a "devia flow" bulkhead to be inserted in a conduct, inside which flows coal with a max flow of 3000t/h, I took into consideration the hardox plates (of precise the 500 series) as they have excellent characteristics of wear resistance........ .
the question is: do any of you tell me, or indicate where to get it, the elastic module and poisson of this material?

in the last, what kind of minute/vite do you recommend me in contact with abrasive materials such as coal?


thanks in advance.

Say hello, swarzy.

Hello, David,

Yes, but the hardox series is not present :frown:


Thank you.

Hello, David,

Yes, but the hardox series is not present :frown:


Thank you.

interesting but I don't find the 2 values that want swarzy

 

[Swarzy]

Hi.

I thank you for the interest...... but I have already been to all the sites you have indicated me!

Marco, I'm already in possession of that datasheet and all the rest taken directly from the Swedish steel mill site ssab... but nothing.

At this point I believe that only those who have already used it will give me the info I am looking for....I am confident!

cmq tomorrow I try to contact hardox italia again, hoping that some technicians have returned from the holidays.

x the screws/minutes, can you give me some info?



Thanks again. :finger:

but sorry, the elastic module and the polka dot coeff are more or less always those, and that's 190-200.000 mpa and 0.3. or do you need precise extreme data?
what changes from steel to steel in a sensitive way are the breaking load and the elongation to yield, but the module and changes very little.

Hello hunter,

Of course what you say is sacrosanct, but since we will most likely go into the final report of fem simulations....better to have official data!

http://www.oxycoupage.com/fichierspdf/english/en_hituf.pdffind the yielding load at 0.2 elongation, from which you can obtain and:

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

rather be careful that you find different values according to sheet thickness. I remember that one had explained it to us but I don't remember why, it seems to me that it had something to do with the lamination process but maybe I'm wrong.

find the yielding load at 0.2 elongation, from which you can obtain and:

forget what I wrote above, that 0.2% represents the deviation from proportionality and not the yielding stretch!

Hi, swarzi, you're seeing each time! ! !
quoto in full the hunt, even because if poisson is not 0.3 is 0.29 or 0.31 and the risutati will change of a quid that is negligible.
If I can find something I'll let you know (I made calculations 4 years ago and I had data that I have now to get from the server - but I'm on vacation)
Hi.

 

[Swarzy]

Hi!

You see, every so much fat, but I'm thick behind the "here."
cmq I have heard a hardox technician (outside home because still in vacation) who told me the same things as hunter, that they should be e= 205000 mpa and v= 0.3

Monday will send me the datasheet with these features.


Can't you tell me anything about screws?


Thank you.
Hi, swarzy.

 

[cacciatorino]

Can't you tell me anything about screws?

time ago I had worked to make the particular development of a machine to cut off graphite residues. the designer had used laminated screws covered with steel caps, so as to restore the continuity of the superifice and not expose the fingerprint of the screw to the wear of the processed materials.

Bye to all,

As promised, I attach the file that was sent to me by hardox italia with the mechanical characteristics of the sheet.


Thank you again! :finger:

Hi, swarzy.

 

[gerod]

Thanks for the doc.
Good job
Hi.
