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.

As with any water softener system, depending on the Hardness of the water, can great affect the average gallons between recharges. Here's the Hardness Specifications SoftSpot Nomad P200: Hardness at 3 PPM yields ~ 1500 gallons Hardness at 4 PPM yields ~ 1200 gallons Hardness at 5 PPM yields ~ 950 gallons Hardness at 10 PPM yields ~ 500 gallons Hardness at 15 PPM yields ~ 300 gallons

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

7Cr17, cheap Chinese steel, equivalent to 440A. Better off buying a quality kitchen knife made of normal steel. This knife is a joke.

Not sure. It is plastic of some kind. Not hard. A little give but not much. Hope this helps.

I would think so since on the Knoop hardness scale glass&ceramic is 400-550, porcelain floor tile is 500-650, and granite is 550-650, tungsten carbide is 2000 and diamond 7000. diamondsure.com/materials.shtml Hope this helps. Charlie

I don't know, but it is a great, I have been filing a piece of 1/4" 3030 stainless steel, I got it because I thought I would break a few before I got the job done, 2 months later it works great, like the day I bought it

Granite has a hardness of 6-7 and the carbide steel point has a hardness of of 8.5 so thepoint should win out. It depends on how detailed a design you are trying to do since thetip will round some in use. There is the heavy duty #9929 point as an alternative.

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

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.

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.

Don't know the grade but it is a very high quality product. My son (a professional landscaper) uses one all the time in his work. I use it in the garden and have nothing bad to say.

I don't know the rating but I fill mine to between 7 and 8. It's a great tire and long wearing.

I think I've seen these rated as 400 on the coarse side and 600 on the fine side. My estimation is that initially they act a bit coarser (say 200/300) but like most polycrystalline diamond abrasives the lose a lot of their aggressiveness after a little use. They do seem to last pretty well for their price. A year ago I bought 4 since they were so cheap and 3 are still in the box. The main defect is the metal abrasive plate tends to separate from the plastic substrate, so they are not good if a very flat surface is critical.
