I looked through my references on tool steels, but didn't find anything for S5. Can you provide additional information such as the manufacturer, tradename, application, state of heat treatment, or chemistry?

Most die repairs I have been associated with are welded with GTAW. I have seen SMAW and FCAW used for large forging dies.

Its hardened tool steel. chemical composition close to S5 and O6. Hardness is near 50 HRC.

Mostly SMAW is used in our industry for welding. The part is rotor and its very small. thickness of build up is 7 to 9 mm on dia of 10 mm.

Do you need the tensile strength or the hardness of the part?
I'd go for a shock resistant filler with similar hardness, preferably on a layer of 307 (18-8-6).
But then again, without knowing the application and operating conditions, not much can be said...

@ gtaw, see attached screenshot from a Budinski book.
