Welding Wire- Hardness

post #1 of 6
Thread Starter 
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

Thanks drew and skippy. I think I got it figured out now.

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.
