Quick Detail

409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other engineering. Due to the presence of austenite grains, its mechanical properties are greatly improved. And due to the addition of many alloying elements, the strength and hardness are also greatly improved. 409 stainless steel is the cheapest model (UK and US) and is commonly used as car exhaust pipes. It is ferritic stainless steel (chromium steel).
