Question:

What is carbide material P30, please?

What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?

Answer:

Cemented carbides are classified into 3 categories, and the ISO standards are defined as K, P, and m three. Each corresponds to the YG class, the YT class, and the YW class in our country. The material properties of P30 correspond roughly to the performance of our brand YT5. Suitable for carbon and alloy steels. But it is not suitable for machining titanium alloy or brittle material, because this kind of cemented carbide with high hardness, good wear resistance, but the strength is not enough, cutting the material easily.
1.p stands for ferrous metals suitable for working long cuts.2.p30 is suitable for working steel, cast steel, long cut malleable iron. Suitable for general rough machining.
ISO (International Organization for Standardization) will be divided into carbide alloy P, M, K three categories, P class equivalent to China's YT class, the main ingredient is WC-TiC-Co;In order to be processed in different cutting conditions of material grade, in the P class with 01-50 number between that from the highest hardness to a series of alloys for maximum toughness between P30, roughly equivalent to the YT5 of our country;This kind of cemented carbide has the highest strength and best impact resistance in YT (P), but it has poor wear resistance. It is suitable for intermittent roughing of general carbon steel and alloy steel.
