I contacted a manufacturer about a the materials of one of their products and they answered the following:

U.S. EQUIVALENT: 1566
% CARBON: 062.-0.7
QUENCHING: NITRATE
EDGE OF BLADE: 48-52 HRC

So, is this good? bad? Average?

I'd appreciate any help, for my knowledge of steel is limited. A few years ago I didn't even know of the existance of High Carbon Steel let alone differrent nomenclatures. :lol:

Have a good day. :lol:

You may have a decent steel to start working with. It will have properties similar to 1060 or 1075. Being in the .6 to .7 range of carbon, it will be tougher but hold less af an edge than the higher carbon steels, but will still harden well enough to make a serviceable blade. Also, I would recommend a oil quench. The high Mn content will cause it to harden quite thoroughly, quenching in water or brine would risk cracking it.

this steel would be better suited to choppers, and axes rather than razors or skinning knives that should hold an edge for a long time. Also, since the Mn will help it harden thoroughly, this would not be a steel to use if you were looking for a Japanese hamon it will be a relatively straight line, and higher than many edge quenches you see.

On a secondary note, Mn also darkens steels quite a bit when hardened, tempered and etched. it would make very black lines in a pattern welded blade.
