[PSUBS-MAILIST] Steel Grade Query

[Jon Wallace via Personal_Submersibles]

You can change the parameters of the calculator to give you an accurate analysis of any steel.  I show 1276 feet max depth for A333Gr3.

Hi All.

I am purchasing battery pods for my new sub.  I am attempting to get
14"NB(355mm) x 98" (2500mm).  Standard weight (9.52mm)

Psubs calculator give ABS depth of 1160 feet (353m) for A516gr70

However, I don't seem to be able to get a516 in that for standard pipe.

I keep getting offered A106grB or A333Gr3 or Gr6.

106 seems to be high temp, 333 low temp.

Does anyone know about these and if they will be ok for battery pods.

Its a lot cheaper to get std wt pipe than it is to get a516 custom rolled......



Many thanks
james
