Hitachi Blue 2 carbon steel / SUS-10 Stainless Cladding Plate 1.8mmX680mm275mm (1/16+”X26 3/4”X10 3/4”)
I guess the steel plate is able to make approximately 10 pieces of 210mm or 240mm chef knives.
It is constructed on 3 layers, and the both outside materials are SUS-10 stainless, and the middle of core steel is Hitachi Blue 2 carbon steel.
We have got it from Japanese steel distributor in Kyushu, Japan.
Blue 2 steel is made by Hitachi Steel Ltd Co. , and it is one of their popular high-end carbon steel
Blue 2 steel composition:
Hitachi blue II steel (C; 1.0-1.1%, Si.; 0.10-0.20%, Mn; 0.20-0.30, P; less than 0.025, S; less than 0.004), Chrome; 0.3-0.5%, Tungsten; 1.0-1.5%
The steel plate is not heat treated yet, and it might be great thickness for kitchen knives, and pocket knives and, thin blades to make.
It is sandwiched by soft iron, so it is easier to sand it down compared with mono steel bar, and protecting bent the blade.
