high carbon steel blades for cutting of basalt fiber (Россия - Тендер #40991893)

We are a manufacturer of basalt fiber (Kamenny Vek) and we produce also chopped basalt fiber. Now we are looking for cutting blades of high carbon steel for our chopping machines. We need blades with parameters shown in the attached file. The thickness should be 0.25mm.
High hardness of the steel is very important! We currently use blades with HRC 63, DIN 1.0618, Germany.
First we would like to order samples (400 pcs) to check that the blades suit our chopping machine and correspond the required parameters.
The cost of blades that we use now is 0,25 USD/pc. The year consumption is approximatelly 30 000 blades.
