What is sintered Stainless steel?
The stainless steel sintering process can produce parts with high strength and wear resistance. Due to the metallurgical bonding between the powder particles in the sintering process, the sintered parts have higher density and strength. At the same time, the characteristics of the stainless steel material itself make the sintered parts have excellent wear resistance and can be used for a long time in harsh working environments.
Features of sintered stainless steel parts
The stainless steel sintering process can produce parts with high strength and wear resistance. Due to the metallurgical bonding between the powder particles in the sintering process, the sintered parts have higher density and strength. At the same time, the characteristics of the stainless steel material itself make the sintered parts have excellent wear resistance and can be used for a long time in harsh working environments.
The stainless steel sintering process can produce complex shapes of parts. Compared with other processing methods, the sintering process can produce a variety of different shapes of parts by changing the shape of the mold, including concave and convex surfaces, special-shaped holes, etc. This makes the stainless steel sintering process advantageous when manufacturing parts with complex structures.
The stainless steel sintering process can also achieve mass production. The sintering process can process a large amount of powder into parts at one time to improve production efficiency. This is very beneficial for industries that require mass production of stainless steel parts.
Sintered stainless steel process flow
The steps of the stainless steel sintering process usually include powder preparation, mold filling, pressing, and sintering. First of all, the stainless steel powder needs to be mixed by a certain proportion and screened and dried to obtain uniform powder particles. Then, the mixed powder is filled into the mold, ensuring that the mold is filled with powder. Next, the mold is pressed so that metallurgical bonding occurs between the powder particles. Finally, the pressed blank is sintered, usually at high temperatures, to ensure the strength and density of the parts.
