Hi Paul,
There will probably be tables
to compare the steel.
The 355 stands for the
yield strength in N/mm2 (Ultimate tensile strength 520 N/mm) It is
very common steel ; exotic material will make the sub more expensive and
probably more difficult to weld.
Lower or higher yield strength
decrease or increase the dive depth.
Pipes are even here in
Inch sizes! The other problem is that you need just very short pieces and you
have to buy lengths. Go with rolled plate!.
Regards, Emile

Onderwerp: [PSUBS-MAILIST] Eurosub
in the Americas
I am trying to
evaluate the prospect of building the new Eurosub here in Canada. Does anyone
know if an ASME or ASTM equivalent exists for the steel that this sub is made
of? It is S355J2, a German standard if I'm not mistaken. How might I account
for any differences in thickness, overall pipe / end cap diameter and steel
engineering properties if I hope to build this sub which uses metric
pipe sizes and a steel standard that I don't believe is available here
either.
