Premium Grade Stainless Steel Powder 316L -325 Mesh (One Pound) Rapid Shipping

I purchased this powder to try out compared to version offered by smooth-on. This powder is much less expensive than theirs, so I figured it would be worth a shot to know for sure what the quality would be. The steel powder comes out to a medium grey, and responds well to a steel wool polish after de-molding. It has a nice shine to it, while still looking dark. In the attached image, the steel casting is on the left, while an iron casting is on the right. You can see the difference!

Didn't think stainless steel metal dust would make much difference in my countertop epoxy. added a pleasant depth to the pour, muting too harsh baselayer colors. Really like the final product.

Measurements from the picture attached/.4 oz = 7.218 cubic inch (powder line was also on the 8 Tablespoon line)383 gram = .84437 lb (this is after zeroing the scale with the glass on it)We know that, Density = mass / volumeThe Density of the powder = .84437 / 7.218 = 0.11698 lb/cubic inchCompare that to the Density of stainless steel 316L = .289 lb/cubic inch.Based on the powder density, I think it is Aluminum Carbide or one if it derivatives. Google that and see the color similarity, also aluminum general density is 0.101 lb/cubic inch.I know SS 316L is considered non-magnetic in the annealed condition, but it can become magnetic under different manufacture process.The fact that I managed to pull some magnetic powder is a good sign of at least having some metal there that reacts to a strong magnetic field.Magnetic or not, does not really mater as much as the metal density. Clamming that this product it is SS 316L is not correct from my point of view. Unless someone can explain this in a better way or put sense into my finding, please let me know.For those who is going to say that the volume is inflated due to the air inside, I have a thought for you. If this was a real SS 316L powder, reversing the calculation will result in the powder you see in the cub should fit in about 3.3 tablespoon volume! I don't see that possible.

As expected.
