I am drawing a blank on some stuff I ordered before. What's the typical hardness of 316L welding wire? 1/8? 1/4? I don't remember ever specifying the hardness before and someone asked and I am sitting here like a dunce.

Not sure how to answer this, hardness-wise, 308L will be easier to bend than 316L, due to a lower hardness, and at .062 thickness are a little over 1/16". Hope this helps.

NOMINAL COMPOSITION:

Carbon .08 % max. Chromium 19.5-22.0 %
Nickel 9.0-11.0 % Manganese 1.0-2.5 %
Copper .75 % max. Silicon .30-.65 %
Phosphorus .03 % max. Sulfur .03 % max.
Molybdenum .75 % max. Iron Balance
Normal Ferrite Range: 5-12


TYPICAL MECHANICAL PROPERTIES AS WELDED:

Yield Strength 61,000 psi Tensile Strength 90,000 psi
Elongation 41 % Reduction of Area 60 %
Charpy V 90 ft/LBS @ room temperature.

Brinell Hardness 180 HB Rockwell B Hardness 89 HRB

I use to use 0.45 316- 360lbs. test great wire I now use 0.47 320 very stiff, 460lbs. test the 316 is a much better price in a 1/4 pound spool, hope this helps

Has anyone ever found 1/16" 308L on a spool? I can get 3' length TIG wire, but there's too much waste, it seems to me. With a spool, you can cut any length you need, no waste till the very last piece. Everyone seems to suggest McMaster-Carr, and they have a lot of stuff, but I've never found 308L in .062 on a spool.
TIA,

You can get a 30# spool of 308L, its around 160 bucks. but I get at least three plugs out of each stick and don't think that is bad. Try Welding Depot.

"Plugs There are about 4,000,000 of these on the market. Not really, but that's just the way it seems(and some guy invented 3 more while I was writing this sentence)from How To Catch Salt Water Fish by Bill Wisner published in1955
