1. Sintered steel is a powder metallurgy iron-based product using pre-alloyed steel powder or mixed powder as raw material.

2. There are two types of sintered carbon steel and alloy steel. Sintered steel is produced by powder metallurgy. A material or product obtained by press molding and sintering steel powder.

The most common method used for sintered steel products is metal injection molding, where very fine steel powder is mixed with a certain proportion of plastic binder and then injected into a mold to become a semi-finished product of any shape, such as gears, bearings, or Case. This process is similar to plastic injection molding, but the injection temperature is slightly higher, but still below 200 ° C. Then the semi-finished product is placed in a high temperature furnace at a temperature exceeding 1000 ° C, which can stick the plastic The cement is burned off while the steel is left.
