Stainless steel 431 is a high chromium-low nickel grade that offers excellent corrosion resistance combined with superior heat resistance and strength. It has the highest corrosion resistance of all martensitic stainless steels and can be used in temperatures up to 870°C (1600°F). Its high tensile strength makes it ideal for heavy-duty applications such as valves, fasteners, and marine components. The main disadvantage of using 431 is that it is unsuitable for welding due to its high carbon content.
One of the primary benefits of 431 stainless steel is that it is more resistant to corrosion than 316 stainless steel. This is due to the higher chromium content in 431 stainless steel, which forms a protective oxide layer on the metal’s surface that helps prevent corrosion.
