Grade 409M exhibits remarkable tensile strength and exceptional resistance to atmospheric corrosion and exhaust gases. Compared to 410 martensitic grades with 12% chromium, SS 409M offers superior performance, including scale resistance at temperatures up to 675℃. These plates excel even under high temperatures, maintaining their integrity and functionality without damage.
Stainless Steel Grade 409M is a ferritic steel widely recognized for its corrosion resistance and mechanical properties, making it ideal for various applications. It is particularly sought after in industries such as pipe manufacturing and automotive, where weldability and resistance to corrosion are paramount.
