Does anybody know the P NUMBER (or S number) FOR TOOL STEEL W1 for procedure qualification?

Thanks

Thanks for the link.
Checked, doesn't seem it is on it.

well tool steel is really not real weldable, least I wouldn't try it.

I guess some folks are set up for it

There is no P-No for this steel. Why do you need one? Just list the base material designation as W1 Tool Steel on the WPS.

Thanks for the reply. One more question, normally what filler material is used for TIG welding this material?

andyweld;
This tool steel is a high carbon low alloy steel that can be welded with local preheat only (300 deg F). I would use a carbon steel filler metal or Inconel (Inco A) depending on the function of the weld.
