409 Stainless Steel

409 stainless steel

409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other projects. Due to the existence of austenite grains, its mechanical properties are greatly improved. And due to the addition of a lot of alloying elements, the strength and hardness have also been greatly improved.

409 stainless steel, the cheapest model (Anglo-American), usually used as an automobile exhaust pipe, is a ferritic stainless steel (chromium steel).
