1. ISO international standards
According to the different scope of applications, the Tungsten Carbide is divided into three classes: P,K,M.
With the continuous development of the TC industry, the naming conventions vary from country to country,
even though the different manufacturers in the same country has different classification of carbide.
P: P01, P05, P10, P15, P20, P25, P30, P40
M: M10, M20，M30，M40
(1) P-type carbide:
The main component of P-type carbide, is WC+ Tic + Co, equivalent to China's YT class.
Mainly used for processing long chips of ferrous metals, such as steel and other plastic materials.
(2) M-type carbide:
The main component of M-type carbide, is WC+ Tic + Tac (NbC) + Co, equivalent to China's YW class.
This type of cemented carbide can not only process cast iron, non-ferrous metals, steel, high-temperature alloys,
but aslo stainless steel and other difficult to process materials. Usually we call it the Universal cemented carbide
(3) K-type carbide:
The main component of K-type carbide, is Wc + Co, equivalent to China YG class.
Mainly used for processing short-cut ferrous metals, such as cast iron, non-ferrous metals and non-metallic materials.
2. Grade in Kone Tool
(1) For woodworking carbide tools:
(2) For packaging industry carbide tools:
