P409L/409CB Stainless Steel

Transcription

1 P49L/49CB Stainless Steel Description P49L/49CB is a ferritic, weldable grade of stainless steel with key performance features, including high compressibility, enhanced green strength and good sinterability. This stabilized grade provides excellent corrosion resistance and has the capacity to provide highcaliber mechanical properties due to the high-temperature sintering response. P49L/49CB 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 HAZ. P49L/49CB is a prime candidate for automotive exhaust system applications, among other uses. 49LNI: has added nickel for new automotive specifications.

5 43L Stainless Steel Low-carbon ferritic stainless steels, in mildly corrosive environments or atmospheric exposures, have corrosion resistance approaching that of some nickel stainless steels. These alloys are oxidation resistant at elevated temperatures. Type 43 alloys are ductile and do not work-harden readily. The toughness defined as resistance to crack propagation or notch strength of ferritic steels is relatively low, and the ductile-to-brittle transition temperature is at or above room temperature. The corrosion and oxidation resistances of the ferritic steels are directly related to their chromium content. The 17% Cr 43 steel alloys have good corrosion resistance to atmospheric conditions. These alloys are used in a variety of applications where corrosion resistance is more important than strength. Corrosion Resistance These alloys are resistant to attack in a wide variety of corrosion media. Resistance to Oxidation Types 43 alloys resist oxidation at temperatures up to 16 F for intermittent service, and from 145 F to F for continuous service. The scale formed is tightly adherent and not easily shed during sudden temperature changes. Since the rate of oxidation is greatly affected by the atmosphere involved, by the heating and cooling cycles, and by the structural design, no actual data can be presented which would apply to all service conditions lbs/in. 3 Specific Gravity Response to High-Temperature Exposure These alloys become susceptible to intergranular corrosion in certain environments when the air is cooled from temperatures about F. The sensitivity to intergranular attack may be accomplished by a decrease in ductility. Normal corrosion resistance and ductility are restored by annealing.
