410 Stainless Steel Sheet & Plate

410 stainless steel, designated as UNS S41000, is a martensitic stainless steel alloy known for its excellent strength and moderate corrosion resistance. This alloy contains 11.5–13.5% chromium and minimal amounts of other elements, making it one of the most commonly used stainless steels for applications requiring good wear resistance, hardenability, and moderate corrosion resistance. It is magnetic in nature and is typically used in applications where both strength and resistance to wear are essential.

Key Features

• Strength and Hardness: 410 stainless steel has high strength and hardness, especially when hardened through heat treatment, making it ideal for structural and mechanical applications where these properties are essential.
• Corrosion Resistance: While 410 stainless steel offers some resistance to corrosion, it is not as corrosion-resistant as austenitic grades such as 304 or 316. It performs well in mild to moderate corrosive environments and can resist atmospheric, water, and mild acid exposures.
• Heat Resistance: It can withstand temperatures up to around 650°C (1200°F) in continuous service, although its resistance to oxidation and scaling is limited compared to more corrosion-resistant alloys like 304 or 316.
• Weldability: 410 stainless steel can be welded, though the presence of high carbon content can lead to the formation of carbide precipitation in the heat-affected zone. Post-weld heat treatment may be required to reduce this risk and maintain mechanical properties.
• Formability and Machinability: The alloy is relatively easy to machine in the annealed condition, but it can become difficult to form and machine once hardened. It is often used in applications that require good machinability and can be hardened after forming.
