201 vs 202 Stainless Steel: Composition, Strength, Corrosion Resistance, Cost & Applications
When comparing 201 vs 202 stainless steel, buyers often focus only on price. However, these two 200-series stainless steel grades differ in chemical composition, corrosion resistance, toughness, workability and long-term application value.
Both 201 and 202 are nickel-saving austenitic stainless steels. They use manganese and nitrogen to replace part of the nickel content, making them more economical than common 300-series stainless steels such as 304. However, lower nickel content also means that their corrosion resistance is usually weaker than 304 and 316 stainless steel.
This guide explains the real differences between 201 and 202 stainless steel, including composition, mechanical properties, corrosion resistance, fabrication performance, cost and application selection.
