Sintered Properties
Sintered properties were determined using test specimens that were sintered for 45 minutes in dissociated ammonia with a -40°F dew point. |

Resistance to Oxidation
Types 430 and 434 resist oxidation at temperatures up to 1600°F for intermittent service, and from 1450°F to 1500°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.

Response to High-Temperature Exposure
These alloys become susceptible to intergranular corrosion in certain environments when the air is cooled from temperatures above 1500°F. The sensitivity to intergranular attack may be accomplished by a decrease in ductility. Normal corrosion resistance and ductility are restored by annealing.
