It's 316, made by fastenal.
Before the overwhelming consensus to ditch this approach, I was thinking that I may have work-hardened it by bending it or perhaps I should just go 1 size thicker, 3/8" instead of 5/16". It seems that since the masthead has the convenient little "ears" to bolt into, why not use them.
Now, I think I may grind those ears off. That way I could easily fit an upside-down U-channel made of stainless to get a solid 2" or 2.5" of extension.
