Nanoflex

Markus, the piece weighs some 3kg. With the additional surface treatment, this test piece is rather special but if it fails to live up to expectations, then the standard treatment will be inferior. I just need to consider the best test for it. I can try a couple of things and will be happy to let you know the results. Hopefully in a few weeks I will get some virgin material of 3.2mm thick, work with that (bend drill and weld it) before heat treating it for final hardness. This is one of its advantages, although in its virgin state is still relatively hard, it can be worked on. Then when you have finished your preperation, put it in an oven at a local fab shop, heat it up and you end up with a material far harder than Hardox 450 but it also remains tough. The sales info suggests that it offers a weight saving over Ti as well.

I have to say that you Swedish may have come up with a rather special material, time will tell.

As I said earlier, Swedish quality...

Tried one test on the Nanoflex yesterday. Approximately 8 tonnes of point force in the centre of the sheet with 2 edges supported. The sheet curved some 20mm in the middle with the force. After releasing the jack, the Nanoflex returned to its original flat shape.

Hehe, quite tough then!

What sort of area was the force applied over. Was it a point load in which case this was very impressive. Or spread over a larger area in which case its still fairly impressive that it returned to its original shape from such a large deformation.

Richard, it was a point force of approx 25mm diameter. I will try it again with a sharp object but I need to find something hard enough first. Any ideas?

High speed steel cutting tip?

Grind up a suitable point on a Cobalt Tool Blank if you have one to hand.

Or use a centre punch.

a ball bearing should do better.
