Stainless steel 410 and 430 are both part of the ferritic family of stainless steels, composed primarily of chromium. Stainless steel 410 is a martensitic grade offering higher strength and hardness due to its carbon content, whereas 430 is a ferritic grade providing good corrosion resistance and formability. Both types are durable and resistant to oxidation, but they differ in chemical composition, mechanical properties, and specific applications. Stainless steel 410 contains more carbon, enhancing its strength but reducing its corrosion resistance compared to 430. On the other hand, 430 is easier to work with and suitable for applications requiring good formability and resistance to aggressive environments.

How to Choose Between Stainless Steel 410 and 430 for Specific Projects

Choosing the right stainless steel for your project is crucial. Let’s break down the differences between 410 and 430.

Ανοξείδωτο χάλυβα 410

• Martensitic grade
• 11.5%-13.5% chromium
• No significant nickel content
• Higher carbon content enhances strength and wear resistance
• Typical uses: cutlery, turbine blades, petrochemical parts

Ανοξείδωτο χάλυβα 430

• Ferritic grade
• 16%-18% chromium
• No nickel content, making it less expensive
• Καλή αντοχή στη διάβρωση και μορφοποίηση
• Typical uses: automotive trim, interior architecture, household appliances

Παράγοντες απόφασης

• Αντοχή στη διάβρωση: Choose 430 for better corrosion resistance in mildly corrosive environments.
• Δύναμη: Choose 410 for higher strength and wear resistance.
