In the end of 2012, the official website already presented some features of the new series, such as:
18+ Vg Max Steel Composition. Vg 10 stainless steel is also a high carbon steel, even though carbon only makes up a relatively small amount of the total material of the blade. En 1.4021 / din x20cr13, widely used in economic cutting tools, 50hrc max after heat treatment.

Vg max steel with a hardness of 61 (±1) hrc forms the entire blade's core right up to its edge. Chemical compositions for common stainless steels. General purpose steel bars for machining, suitable for lightly stressed components including studs, bolts, gears and shafts.
It sounds like they added a little more of everything:
At this level, there is less variation in initial tap compositions and required casting times, making it easier for you to repeat the simulation. Quite often our customers will ask us about the different types of steel we sell, and what to look for when picking steel grades, shapes and sizes. Good wear resistance and rust resistance. Mechanical properties in cold drawn condition.
