what is the hardness rating (A)
707090
I don't know what the rating is but they didn't last long for my son. Maybe 3 weeks.

I am not understanding the nature of your question fully. At any rate I will attempt to answer to the best of my ability. It is a lil trick applying the wheels but you can find a good youtube video to assist you. That is what my son did to put the wheels on himself and he was 13 at the time. I hope I answered your question to satisfaction. All the best to you and Happy Safe Ripstik riding.

It is a sharping steel, but I have no idea what numbers are for hardness? It is not diamond coated.

Not sure what its rated for, but I'm 200-210 and no problems...been using these for years, one at work, one at home.

Rockwell hardness test: the minor load is 3 kgf and major loads are 15, 30, or 45 kgf hardness test. the amount of pressure that the steel will be subjected to before a depth is made on the surface of the blade.

I don't know about the grade of stainless steel. I do know it is very durable and very sharp!

I would say probably A to A-.So far almost all of mine had no cracked ones in it. These actually are the Polycrystalline Silicon Solar Cells. I plan to buy another box as soon as I can. I always expect some to get chipped in shipping, but generally A to A-. Grade A is for perfect. Grade B is for some chipped or cracked, but still give almost full output. Grade C is for more broken and chipped, if didn't you already know.

From the Buck Knives site "it can be hardened to a Rockwell hardness of Rc 59.5-61."Second hardest steel I know of for knives.

The first number is always "18" so by itself, it means nothing. 18/10 is high-quality rust resistant and not magnetic. 18/0 is less "stainless" but it is magnetic and works on induction hobs. Often, with a multi-ply pan, the inner layer will be 18/10 for stain resistance and the outer layer will be 18/0 to work on induction hobs (the layer in between would be aluminum or copper.

I don't know the grade. Probably B or C, not counting a few that cracked during shipping.

About .2 grams. That's the lowest weight that I've found that it will respond to. Which is within its rated accuracy of + - .2 grams.

I believe this stainless is 18/10. I can't be sure because I'm in the middle of a move and all my paperwork -- and the pans themselves -- are packed away for a few months. But they do have a respectable nickel content. The pans themselves have proven to be excellent at resisting all kinds of stains in the time I've owned them.

That is a grading for the condition of the part.For instance. .. A ...is the best. ... B ... is the next best. ... C is the next best and so on.

My guess is 7 or 8 based on the arrestance valueSource: http://www.mechreps.com/PDF/Merv_Rating_Chart.pdf

The load rating would determine the # of plies generally, 10 ply would be the E rated. General tires were always US made, I think they still are but these days you never know for sure.

H.A. Hard anodization process alters and hardens structure of Cookware surface making it abrasion resistant I've only used it once thus far so I can't really confirm it.

I found a chart by searching 42hs4013a4, it seems to indicate 5mm, with a tolerance of 0 to -0.012.
