Fe50 iron base alloy powder

Feature Description:

The powder is a stainless steel iron - based self - fusible alloy powder containing high Ni - Cr and Mo. It contains fairly high levels of nickel and chromium. Therefore, it has better spray welding process performance, corrosion resistance and oxidation resistance. The addition of a small amount of molybdenum can improve its seawater corrosion resistance and point corrosion resistance, and improve the strength and toughness of the welding layer, red hardness and high temperature corrosion resistance, and refine the grain.

Main uses and processes:

It is recommended for wear and corrosion resistant welding layer below 500ºC, such as scraper, axle, agricultural tools and so on. Suitable for oxyacetylene spray welding process, plasma surfacing welding, spray welding process.
The powder used for sintering iron base and gold valve disc has excellent formability and abrasion resistance, and does not precipitate carbides which may wear the fitting members. A powder can be provided, which is used as prior art gas atomization method, water atomization method, centrifugal atomization method, etc. to quench the liquid steel, forming a susaturated solid solution of the following alloying elements with austenite as the main body which is effective in softening the powder, wherein the liquid steel by controlling C as an unavoidable impurity element to less than 0.1 mass %, and avoiding carbide precipitation , containing Si:0.5 ~ 8.5 mass %,Ni:10 ~ 25 mass %,Mo:5 ~ 20 mass %,Co:5 ~ 20 mass %, the rest of the composition of Fe and inevitable impurities. The powder has excellent formability during compression forming due to its low hardness. On the other hand, it has excellent abrasion resistance in the valve piece of the final product due to hardening after sintering. In addition, since no carbides are precipitated, there is no need to worry about wearing the fit member.
