TLDR;
Can you please help me understanding the string in the picture and help me finding the yield stress that my metal can handle?
Full story
I am trying to estimate how much load some zinc-coated steel pipes that I bought can handle.
This webpage provides a calculator in which I specify 6 parameters and I get estimated if my tube will fail or not. I know 5 out of 6 parameters for my system; what I lack is what they call the yield stress (measured in PSI, see the table near the center of webpage for some example of yield stress values).
Examining my pipe I found a string (see picture); is this enough to identify the yield stress of my pipe?
The best I got so far is that by googling "EN 10255 steel" I land into this webpage from which I think that one can deduce that (I stress the fact that I am not sure about the following) the "Upper Yield strength $\text{R_eH min.}\ (MPa)$" is 195 (which amounts to $\approx 28282\ \text{PSI})$.
Beside not being sure if the number above is the one I am looking for, in the picture you can read also other numbers, which seem to correspond to other steel types. Maybe my steel is an alloy?
So my question:
Can you please help me understanding the string in the picture and help me finding the yield stress that my metal can handle?
The string
This is the string I read from the picture
JTL-33.7 OD-L2-EN 10255/ EN 10219/10240/A1-W-20-0436-CF
I am not sure if the last letter is a F
or a E
. 33.7 is the outer diameter of the pipe.
Where I bought the pipe
I bought the steel pipe from Hornbach (Germany), here is the webpage for the steel. The diameter is 33.7 mm, the wall thickness is 2.65 mm and it costs ~ 7€ per meter. Notice that it is written that the pipe is not suitable for load bearing structure/scaffolding, just for building furniture. But still I would like to know exactly how much load it can hold, since also furniture will have to stand some weight.
