>400 series stainless?

I've been here quite a long time actually, but generally kept quiet mainly
because this is an EFI discussion group, but I will try to help people or
point them in the right direction 'off-line'.

Mail me direct if you have a specific question about the 400 series (but
generally these are the martensitic/ferritic grades with the martensitic
being the 'hardenable' version - eg type 410 - ; they are used for steam
valves, bolts, furnace parts, etc, etc.; not recommended to be welded due
to a high risk of cracking in the heat affected zone[HAZ])
