| P409L/409CB is a ferritic, weldable grade of stainless steel high compressibility, enhanced green strength and good sinterability. This stabilized grade provides excellent corrosion resistance and has the capacity to provide high-caliber mechanical properties due to the high-temperature sintering response. P409L/409CB’s versatility also results from Cb being less prone to oxidation than Ti. In addition, the oxide is unable to combine with carbon and the Cb forms a stable carbide which prevents coarsening of carbides and grains in the weld’s heat-affected zone. P409L/409CB may be used in automotive exhaust system applications, among other uses. For property data reported here: Compacting properties measured on powders with 1% lithium stearate. Sintering was done in dissociated ammonia at 1121°C (2050°F) for 45 minutes. Compacting pressure 40 tsi. Green strength 1800 psi. Sintered breaking strength105,000 psi.
