What are the Advantages of Stainless Steel Powder Metallurgy?

What is stainless steel powder metallurgy?
 
Stainless steel powder metallurgy is stainless steel manufactured by powder metallurgy. It is a powder metallurgy material that can be made into steel or parts. Stainless steel powder metallurgy is widely used in machinery, chemical industry, shipbuilding, automobile, instrumentation and other industries because it can save raw materials and energy consumption, and achieve low carbon, green and environmental protection.
 
What are the advantages of stainless steel powder metallurgy?
 
1. The corrosion resistance of stainless steel powder metallurgy
 
Corrosion resistance refers to the ability of stainless steel to resist corrosion damage by medium. Corrosion resistance includes rust resistance and resistance to corrosive media such as acids, alkalis, and salts, as well as resistance to oxidation, vulcanization, chlorination, and fluorination at high temperatures. In choosing powder metallurgy stainless steel, besides paying attention to the general corrosion resistance of stainless steel, it is also necessary to pay attention to the local corrosion under specific conditions of use.
 
2. Mechanical properties of stainless steel powder metallurgy
 
Powder characteristics, sintered body density and sintering parameters determine the mechanical properties of powder metallurgy stainless steel. For example, the production of medium-density stainless steel (6.2-3.6g/cm3) is usually pressed at 415-825MPa, at 1120-1150 degrees Celsius, decomposing ammonia, hydrogen or sintering in vacuum. Sintering at a higher temperature of 1260-1315 degrees Celsius can obtain excellent elongation, impact toughness and corrosion resistance.

 

3. Machinability of stainless steel powder metallurgy
 
The machinability of sintered stainless steel is the same as that of forged stainless steel. High temperature sintering and sintering in hydrogen or vacuum improve cutting. When sintering in a nitrogen-containing atmosphere, the hardness will be higher due to nitrogen absorption, which will impair the machinability. In industrial production, manganese sulfide can be added to 304L to improve machinability.
 
The common materials of stainless steel powder metallurgy are 304, 316, 420. 304 is universal stainless steel, non-magnetic, has good comprehensive performance, and has strong corrosion resistance. 316 stainless steel powder metallurgy is non-magnetic, and Mo is added to make it corrosion resistant. , And the high temperature strength has been greatly improved, and it can be used under harsh conditions. 420 is generally called stainless iron, weak magnetic, has certain wear resistance and corrosion resistance, high hardness, etc., can be heat treated and hardened.
