Stainless Steel Powder
Stainless Steel Powder
Water Atomized Stainless Steel Powder
Applications：
- Lock parts and in appliances
- PM stainless steel parts in different areas, as small gears, cams and connectors
- Automotive exhaust flanges and hot exhaust gas oxygen sensor bosses
- ABS sensor rings…
As powder metallurgy (P/M) grows, stainless steel becomes more common, we have increased our investment in stainless steel powder production capacity and technology. All our PM steel powder optimised for compaction and sintering/heat treatment,good mechanical properties, corrosion resistance.
The 300 Series Powders are austenitic stainless steels powder ,typically used for powdered metallurgy (P/M) press and sinter applications to make near net shape parts for a variety of industrial applications.
The 400 series powders are ferritic stainless steel powders with good atmospheric and salt water corrosion resistance, thermal oxidation resistance and high temperature yield strength, the most economical way to manufacture automotive components is to use 400 series stainless steel water atomized powders. Typical automotive components requiring 400 series powders include rear-view mirror mounts, sensor rings, exhaust flanges, exhaust support brackets, and seals.
