as always intent on "sfrugugnare" between old carrettes and just old dies, I came across the name "steel v2m" which, I admit my ignorance, I had never heard of.
after a rather long research on the net, I find a correspondence with steel 20mn6 (uni) or 20mn5(din).
could you confirm if this type of steel is currently called p305gh according to the uni en 10222-2 and possibly where to find the mechanical characteristics (I do not have such a standard uni en)?
Thank you all.
 
I'll see you.
from the gospel according to the mechanical constructor (?) the 20mn5 (equivalent to v2m) should now be the 17182 din with yield voltage between 500 and 650 n/mm2.
If I find out other findings, I will:-)
 
Hello exatem,
Honestly I did a research but I didn't find anything new.

I also checked in the company archive if there was the norm you mentioned but nisba

Thank you. It's all day I've been spraying like a liner between ancient scriptures, sacred texts and bibles assorted but besides what I posted, I find nothing else.
I specialized in "introvable" as when I was looking for flanges out of norm since 1942...
Mine must be a genetic deviation.
 
to me it turns out
v2m according to uni 5771 of 1966 corresponds "about" to wk. 1.0469 which is a 21mn4 (din) or 20mn4 (uni)
c from 0.16 to 0.24
from 0.10 to 0.25
mn from 0.80 to 1.10
max 0.035
max 0.035

but I do not find mechanical characteristics. . .
 
I don't promise to find anything, but tomorrow I try to see on the "stahlschlüssel" and if I find I tell you...

So I have this genetic deviation sometimes... :smile:

Unfortunately, I cannot help you for the absolute lack of time, as I did on the flanges.

As soon as I can, if you do better for yourself.
Hi.

p.s.
If it's something very old, look for hope, did you?http://augusto.digitpa.gov.it/#giorno=1&mese=1&anno=1862
 
I found a match qui, ie v2m=20mn8 (? )
But on 20mn8 I can't find him anywhere, I'm looking for the old man in the office tomorrow and see if I find anything.

Bye.

Did you find the reference to the v2m on a petroglyph? :smile:

almost on the rosette.:biggrin:
last night I found a 1975 catalogue of valbruna steels and on page 85, among the rectification steels here is the mysterious v2m.
is indicated as high yielding steel, particularly recommended for welded parts.
the table shows the names: uni 20mn6; sae/aisi/astm 1022; afnor en14ar and din 20mn5.
 
I on the "stahlschlüssel" found the "din 20mn5" (1.1133) with all its features. ...

enigma

do you need the features?

Yes, I would need to know yielding and breaking and if possible, a current designation.
I have to reconstruct a "totem" on which a trailer hook works and I need to indicate a steel with identical characteristics (or at least similar).
but I would like a more recent denomination of v2m since no one knows her...

stahlschlussel goat.. .
yesterday I also looked for myself, and as a result gave me as correspondence "about" wk. 1.0469 which is a 21mn4 (din) or 20mn4 (uni)
 
in the sense that I questioned him yesterday and he gave me a result.
Today you're interrogating him and you're from another.. .

What version do you have? I have 2010, but the "correspondences" should always be the same.
Or not? ?
 
aaaaahhh.. .
I left the v2m

However it is curious the same that you do not get to the same correspondence, although in fact differences are negligible
more formal than practical

Thanks, guys.
in conclusion is a 20mn5 din and I think it is a steel of not easy availability in Italy.
I'm going to have to throw myself on an equivalent (as characteristics of yielding and breaking) more commercial.
suggestions?
