Stainless Steel 201 / 202 Sheets & Plates

What are Stainless Steel 201 / 202 Sheets & Plates?

Stainless Steel 201 and 202 sheets & plates are austenitic stainless steels belonging to the 200 series, known for their low nickel content and cost-effectiveness. These grades use manganese and nitrogen as substitutes for nickel, making them more economical compared to 300 series stainless steels.

They are widely used in applications where moderate corrosion resistance and high strength are required.

Key Functions:

• Used in fabrication, construction, and industrial applications
• Provide strength and durability
• Offer aesthetic appeal with polished finishes
• Suitable for forming, welding, and machining

Chemical Composition of SS 201 / 202

Stainless Steel 201:

• Chromium (Cr): 16% – 18%
• Nickel (Ni): 3.5% – 5.5%
• Manganese (Mn): 5.5% – 7.5%
• Nitrogen (N): ≤ 0.25%
• Carbon (C): ≤ 0.15%

Stainless Steel 202:

• Chromium (Cr): 17% – 19%
• Nickel (Ni): 4% – 6%
• Manganese (Mn): 7.5% – 10%
• Nitrogen (N): ≤ 0.25%
• Carbon (C): ≤ 0.15%

Higher manganese content improves strength and reduces cost.

Corrosion Resistance

SS 201 / 202 sheets and plates offer moderate resistance to:

• Atmospheric corrosion
• Mild chemical environments
• Indoor and dry conditions

They are less resistant than 304 stainless steel and are not recommended for highly corrosive or marine environments.

Heat Treatment

• Not hardenable by heat treatment
• Can be strengthened through cold working

Annealing Process:

• Temperature: ~1010–1090°C
• Rapid cooling

This improves ductility and corrosion resistance.

Weldability

SS 201 / 202 offer good weldability.

Welding Methods:

• TIG (GTAW)
• MIG (GMAW)
• Spot welding

Best Practices:

• Use proper filler materials
• Avoid excessive heat input
• Maintain clean surfaces

Machinability

• Moderate machinability
• Use sharp cutting tools
• Maintain proper speeds
• Apply coolant
