Performance Characteristics
Corrosion Resistance
Provides good resistance to atmosphere, foods, fresh water, and mild acids when hardened and surface finished. Resistance is lower than austenitic grades and decreases in annealed condition.
Heat Resistance
Not recommended above 800°F (427°C) due to mechanical property reduction. Scaling temperature is approximately 1202°F (650°C).
