    I do not know which stainless rod we use but I can ask.
    I have welded 100's of dies in a few stamping plants. Air hard tool steel rod is used most of the time. Unless the dies are older and need water or oil hard filler. I would like to know what SS filler you use also...Bob

    This is done for two reasons. One being that we don't have enough time to do a proper repair with a steel filler rod designed for the tool steel used on trim dies/sections. The other is when the area to be repaired is difficult/impossible to reach.

    Although these repairs are considered short term/temporary until sufficient time to repair properly, it is surprising how well the weld does stand up.

    Difference between Stainless 308 and 309:
    • SS309 is a better choice for welding mild steel to stainless or unknown to unknown.
    • the 309 has more Chromium and Nickel, which helps avoid problems with cracking.
    • Using 308 on mild steel can result in weld bead cracking if the dilution with the base metal is not right.
    • 309 is a carbon to stainless rod 308 is stainless only
    • 309 is more versatile.
    • 309 has better mechanical properties.
    • 308 has more uses. be sure to buy 308LMo though.
    • 309 is for stainless to carbon steel and buttering stainless.
    Well, that's an odd post. Looks cut-and-pasted from somewhere, but three of the bullets say pretty much the same thing, others are contradictory without the specifics of the situations. Can you add which apply to the thread in question re tooling?

    If you are doing Tool and Die welding 308 or 309 would be about the LEAST often used filler. From experience.

    Tool and Die shear blades aren't 308 or 309...Bob

    Stainless 308 and 309

    I am in the tool and die field and I have a question if anyone can help. Now and then we have to shear tooling in using 308 stainless. We ran out of 308 so I used 309. Will there be any difference between the two when used for shearing took steal. Thanks.
Working...
