what’s the difference between 410 &410S stainless steel

The main difference between 410 and 410S stainless steel lies in their carbon content and their intended applications.

410 stainless steel is a general-purpose stainless steel that contains a minimum of 11.5% chromium. It offers good corrosion resistance, high strength, and hardness. It is often used in applications that require moderate corrosion resistance and high mechanical properties, such as valves, pumps, fasteners, and components for the petroleum industry.

On the other hand, 410S stainless steel is a low-carbon modification of 410 stainless steel. It contains a lower carbon content (typically around 0.08%) compared to 410 (0.15% maximum). The reduced carbon content improves its weldability and makes it more resistant to sensitization, which is the formation of chromium carbides along the grain boundaries that can reduce corrosion resistance. As a result, 410S is better suited for applications where welding is required, such as annealing boxes, furnace components, and other high-temperature applications.

In summary, the main differences between 410 and 410S stainless steel are the carbon content and their respective applications. 410 is a general-purpose stainless steel with higher carbon content, while 410S is a low-carbon variant that offers improved weldability and resistance to sensitization.
