SUS201 Stainless Steel: Budget-Friendly Austenitic Alloy Option

Key Characteristics

Composition: High Manganese/Nitrogen, Low Nickel (about half of 304), Chromium.

Cost: Cheaper than 304 grade due to lower nickel content.

Strength: Higher tensile and yield strength than 304 due to work hardening.

Appearance: Non-magnetic when annealed, becomes magnetic when cold-worked.

Corrosion: Good atmospheric resistance but inferior to 304; prone to rust in harsh, salty conditions.

Common Applications

Kitchen Sinks & Utensils

Automotive Trim & Window Frames

Decorative Panels & Furniture

Springs, Clips, Fasteners

Indoor Plumbing & Mild Chemical Environments

201 vs. 304

Choose 201 for budget-conscious projects needing strength and good looks for indoor or light-duty use (e.g., appliances, decorative trim).

Choose 304 for superior corrosion resistance and durability in more demanding environments (e.g., outdoor furniture, food processing equipment).
