Resistance to Corrosion
Type 301 is resistant to a variety of corrosive media. However, the corrosion properties are not as good as the 18-8 chromium nickel steels. Its susceptibility to carbide precipitation during welding restricts its use in many applications in favor of Types 304 or 304L.
Resistance to Oxidation
Type 301 possesses good resistance to oxidation at temperatures up to 1550°F (840°C). At 1600°F (871°C), Type 301 exhibits an oxidation weight gain of 10 mg/cm2 in 1,000 hours. Therefore, this stainless steel is not suggested for use at 1600°F or above. As the rate of oxidation is greatly affected by the atmosphere to which the metal is exposed by the heating and cooling cycle, and by the structural design, no data can be presented which will apply to all service conditions.
