It has high hardness, but lower bending strength. It has a low clingability with steels. Works on steels with virtually no buildup. It is used for (finishing and semi-finishing turning and milling of low-alloyed, carbon steels, cast iron and non-ferrous alloys). Wear resistance is 1.2 — 1.5 times higher than that of alloys of the TK group. Disadvantage — poorly solder and sharpening
