OMana Handpan. D min8 (HP N2).
Ones we decided to combine two of our technologies into one new. We took our steel that we use for HP (HardPan) instruments know also as Golden Type and made the nitricarbonization (N2) treatment for it. We did lots of test with it and had great number of fails. This way is quite tricky and gives sometimes a very unpredictable result. But we found a way. Now it have nice tight somewhat compressed a smooth flowing sounding and nice corrosion resistant surface.
