JM Steel 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 have been greatly improved. And due to the addition of a lot of alloying elements, the strength and hardness are also greatly improved.409 stainless steel, the cheapest model (British and American), is usually used as a car exhaust pipe. It is a ferritic stainless steel (chrome steel).
·Standard：AISI, ASTM ·UNS：number S40900 ·Application：as a car exhaust pipe
