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.

I believe it refers to gauge/weight of the stainless steel.18/10 is a good grade.

Joe, There is no documentation regarding the grade of aluminum. My guess is that it isn't "tool grade" aluminum.

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.[1] There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter. When testing metals, indentation hardness correlates linearly with tensile strength.[2] This important relation permits economically important nondestructive testing of bulk metal deliveries with lightweight, even portable equipment, such as hand-held Rockwell hardness testers.[citation needed] 3 Scales and values

I do not have the chart, unfortunately they can become damaged very easily, sorry

I believe there is no difference as far as levels of hardness, just a different choice of colors.

The core of the blade is VG-10 hardened to Rc 60-61 with a softer outer layer of stainless. In other words a clad knife . This allows the cutting edge to be harder but the over all knife to be tougher and not break or chip as easily .

I believe that rating only applies to the data lines. if you look at the spec page on apc you will find this rating comes directly after data line protection and data lines protected.

I agree with the other response, there is no documentation regarding the grade. I have used it regularly and it appears to be very sturdy.

Im not sure what its rated but at 185 it was good for about a month and then the base split like crazy and the shaft went completely through it. DO NOT BUY IT!!!!

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.

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

Sorry. I have no idea. I didn't know there were different grades. It seems plenty heavy enough. I read several years ago that there may be a connection to using aluminum and alzimers so I have changed to all stainless steel cookware.

Not sure what type of beech or hardness number but I use it to make chopped liver in and I use something similar to a mezzaluna for the task . Seems sturdy enough for this . I bought it to replace a bowl that developed a slight crack in the bottom after over 20 years of service and so far I am happy with it .

Not sure of the actual hardness but it is pretty soft. More dense and less porous than a wetsuit neoprene but probably softer. Hope that helps!

I'm not sure what grade they are, but they are the best drill bits that I have ever bought. They work very well, and stay sharp, even after using. I hope this helps.
