How does powder metallurgy injection molding produce iron powder with low oxygen content?

Daehong new materials found that the atomization method can be used to produce iron powder with low oxygen content. In the environment without oxygen, some paraffin was added, which decomposed into carbon and hydrogen, and carbon would react with iron to form a carbon-rich protective layer on the surface of iron powder. Although carbon decreases the ductility of particles, it greatly improves the surface sintering activity of iron powder.

In powder compacts, carbon is easily diffused into the interior of particles and adjacent particles to achieve powder metallurgical steel without graphite. Injection molding companies have found that for powder metallurgy applications, the oxygen-free powder can be used to replace strategic metals such as nickel and copper with chromium and manganese, as well as to produce high-strength parts using warm and hot pressing processes.

In a word, MIM experts of daehong new materials have concluded that atomization method can be used to produce iron powder with low oxygen content through verification. I hope the above conclusion can be helpful to everyone!
