Filler electrode for repair welding of Tool steel S5 or 06

Filler electrode for repair welding of Tool steel S5 or 06

Filler electrode for repair welding of Tool steel S5 or 06

(OP)
I am going to buildup on tool steel s5/06 for repair purposes, i have limited option of using electrodes which includes E8018-B2L and E12018M. I have also E309 and inconel.

From my point of view in order to have good tensile strength i should use E12018M or E8018-B2L (2nd preference).

Please give your suggestions. Thanks!

RE: Filler electrode for repair welding of Tool steel S5 or 06

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.

RE: Filler electrode for repair welding of Tool steel S5 or 06

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.

They've helped me out in the past with custom stainless steel formulations.
