Description:

Tungsten steel is formed by pressing the powder into a billet, heating it to a certain temperature (sintering temperature) in a sintering furnace, and maintaining it for a certain period of time (heating time), and then cooling it down to obtain a tungsten steel material having desired properties.
The four basic stages of the tungsten steel sintering process:
Removal of the forming agent and the pre-firing stage, in which the sintered body undergoes the following changes

The removal of the molding agent, as the temperature increases, the molding agent gradually decomposes or vaporizes at the initial stage of sintering, thereby eliminating the sintered body. At the same time, the molding agent more or less carbon is added to the sintered body, and the carbon addition amount will follow the molding agent. The type, quantity, and sintering process vary.
The surface oxide of the powder is reduced. At the sintering temperature, hydrogen can reduce the oxides of cobalt and tungsten. If the molding agent is removed by vacuum and sintered, the carbon-oxygen reaction is not strong. The contact stress between the powder particles is gradually eliminated, the bonded metal powder begins to recover and recrystallize, surface diffusion begins to occur, and the strength of the compact is improved.

Application:

High-hardness steel parts (hardness above HRC45)

Such as high-manganese steel, high-speed steel, hardened steel, high-frequency hardened steel, tool steel, bearing steel, etc. Typical parts include rolling mortar wall, high-speed steel roll, hardened gear/gear shaft, bearing, ball screw, mold, etc.

Ordinary gray cast iron (HT150/200/250/300, etc.), high hardness cast iron
Such as engine block/cylinder head, brake disc, brake drum, pulley, clutch pressure plate, etc. are all gray cast iron parts. Use CBN material series cutters. High processing speed, effective cost saving, such as high chromium cast iron, alloy cast iron, nickel hard cast iron, white cast iron are all high hardness cast iron, typical parts include rolls, industrial pumps, etc. Advantages of CY1 and HJ3 series materials commonly used for high hardness cast iron. It can pull out rough castings with sand and pores.
