Sintered Parts

Machine structural components made by powder metallurgy called sintered mechanical structure parts, referred to as sintered structural parts.
Sintered Fe-Cu Alloy and sintered Fe-Cu-C are the most application in the production of sintered structural parts.
Sinfine sintered nickel-steel parts have a relatively wide range of production applications.When the Ni content of sintered nickel steel below 15%, the mechanical properties increase with the Ni content increasing; while it is more than 15%, tensile strength reducing because of the Ni content increasing. The tensile strength of containing 25% Ni is same as 5%. Nickel scarce, prices high, generally for sintered parts manufacturing, the Ni content is not more than 5%.
Sinfine Fe-C alloy choosing the natural graphite of low ash content and small particles, for which with strong reaction and easily dispersed.
This sintered Fe-C alloy.This sintered Fe-C alloy subject to strong response to reduce the iron oxide and cabon rapidly;
Easily dispersion that mixed powder with good mobility and have a wide mix temperature range.
When adding the alloy elements Mo into Sinfine sintered nickel steel, it can further increase the tensile strength. With more Molybdenum is mainly to increase the hardenability of sintered alloy. The combination of Ni and Mo can effectively prevent the pearlite transformation when cooling. Alloy steel contains Ni, C and Cu are to some extent the role of stable austenite.

The Mo, Si in Sinfine stainless steel with the function of ferrite stability, for which it can change unstable austenite
in powder particles into martensite in the compacting processing, powder particles hardening and pressing deterioration.
Since Ni is an effective element for austenite stability , so taking the content of high nickel and low carbon to prevent particles hardening and improve the powder particles compacting.
