AWS A5.4: E307-16 rods: why in vacuum bags?
(OP)
The manufacturer is asked to deliver following rods in a vacuum bag (sahara pack):
E 18 8 Mn R 73 (according to EN1600)
E 307-16 (according to AWS A5.4)
rebake: 2h at 300°C
Specs come from their website.
designated usage: welding Hadfield steel.
Why are they asked to deliver in a sahara pack?
These rods aren't of the basic type, however I cannot find anything about their H2-content. Are they low-hydrogen rods?
I'd like to have some background info ready when I call them, hance I ask this question here first.
Thanks in advance!

I prefer to keep my stainless SMAW rods in a 'warm', just hot enough to stay well above the dew point. Do NOT put them into the hot oven -- 250°F / 110°C minimum that low-hydrogen rods must be kept in.
