Stainless 301 Type 301 (S30100) is an austenitic stainless steel with a nominal composition of 17% chromium and 7% nickel. The high strengths of this grade of steel in the six available conditions or tempers, its resistance to atmosphere corrosion and its bright, attractive surface make it an excellent choice for decorative structural applications. By varying the chemical composition within the limits set by the ASTM specifications and by temper rolling, a broad range of magnetic and mechanical properties can be obtained for a variety of applications. 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) it exhibits an oxidation weight gain of 10mg/cm2 in 1,000 hours. Therefore, this stainless steel is not suggested for use at 1600°F or above. Features • Provides good strength and ductility when cold worked • Has excellent corrosion resistance • Well suited to welding and forming and drawing • Attractive surface Applications • Aircraft Structural Parts • Trailer Bodies • Architectural (roof drainage/door frames, etc.) • Auto body trim wheel covers • Utensils and tablewear
