Stainless Steel Powders | 400 Series

Ferritic stainless steel powdered metallurgy (P/M) technology is specified for longer-term performance and reliability. Good atmospheric and saline corrosion resistance, hot oxidation resistance and elevated temperature yield strength, at the most economical costs are key reasons for using 400 series stainless steel water atomized powders to make automotive components.
Typical automotive components requiring 400 series powders include rear-view mirror mounts, sensor rings, exhaust flanges, exhaust support brackets, and seals.

•409 is a ferritic, weldable grade of stainless steel offering high compressibility, enhanced green strength, and good sinterability.  

•410 is a magnetic grade of stainless steel exhibiting fair corrosion resistance and decent high temperature sintering response as well as good green strength and high compressibility.  

•430 is a low carbon ferritic stainless steel used in mildly corrosive environments and is oxidation resistant at elevated temperatures.  The material is ductile and does not work harden readily. 

•434 is a low carbon stainless steel used in mildly corrosive environments similar to 430.  This alloy is used where corrosion resistance is more important than strength.
