301 Stainless Steel

301 Stainless Steel is a modification of 304 stainless. When cold worked, it provides a high strength and ductility for a variety of applications. This material is available in a variety of tempers including 1/4 hard, 1/2 hard, and full hard depending on end use. Common applications for this material include auto body trim, utensils, aircraft parts, and architectural products.

Type 301 exhibits corrosion resistance comparable to Types 302 and 304 in the mild service conditions. Resistance to atmospheric corrosion, food, juices and road de-icing salt is excellent. The best corrosion resistance is obtained in the annealed condition.
Type 301 is non-harden able by heat treatment. Annealing: Heat to 1900 – 2050°F (1038 – 1121°C), then water quench. Stress Relief Annealing: Heat to 500 – 900°F (260 – 482°C), then air cool.
