409 stainless steel is a ferritic stainless steel commonly used in machinery, construction and other engineering. 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 are also greatly improved. It has good mechanical properties and high temperature corrosion resistance. It contains 11% chromium, the minimum required to form a passive surface film that makes stainless steel corrosion resistant. It combines good high temperature corrosion resistance with moderate strength, good formability and overall cost. We can provide the following form:409 stainless steel coil; 409 stainless stee strip;409 stainless stee plate; 409 stainless steel sheets; 409 stainless steel tubes; 409 stainless steel pipe; 409 stainless steel flat; 409 stainless steel bar 409 is most commonly used in truck exhaust systems, agricultural equipment, and heat and gas turbine exhaust silencers.
