410 vs 201 Stainless Steel: Strength and Corrosion Trade - offs

 

How do their chemical compositions stack up?​

410 is a martensitic steel with 11.5 - 13.5% chromium and 0.15% carbon. 201 is an austenitic steel with 16 - 18% chromium, 3.5 - 5.5% nickel, and higher manganese for cost - effectiveness.​

 

Which has better strength characteristics?​

410 can be heat - treated to achieve high strength and hardness, great for wear - resistant parts. 201 has lower strength but is more ductile in its as - received state, suitable for forming into simple shapes.​

 

How do they resist corrosion?​

201 has better corrosion resistance in normal indoor and low - humidity environments. 410's higher carbon reduces its corrosion resistance, making it more prone to rust in damp conditions.​

 

What about their magnetic properties?​

410 is magnetic due to its martensitic structure, useful for applications needing magnetic materials. 201 is non - magnetic or weakly magnetic, suitable for applications where magnetism is not desired.​

 

Where are they commonly used?​

410 is used in knives, valves, and pump components where strength and wear resistance are crucial. 201 is found in decorative items, kitchen utensils, and low - cost furniture due to its cost - effectiveness.
