409 stainless steel, the cheapest model (Britain and the United States), is usually used as a car exhaust pipe, which is ferrite stainless steel (chromium steel).
409 Stainless Steel Standard
The manufacturing of 409 stainless steel mainly follows the standards of AISI and ASTM in the United States. Generally, the carbon content of 409 stainless steel is less than or equal to 0.03, and the content of CR is between 17.0-19.0.It is greater than or equal to 175, the tensile strength is greater than or equal to 360, and the extension rate is greater than equal to 25%.There are many elements contained in 409 stainless steel, including carbon, silicon, chromium, nickel and other substances. The highest content of each material is: carbon: C≤0.08, manganese mn: ≤ 1.00, silicon SI: ≤1.00, chromium CR: 10.5 ~ 11.75, nickel Ni: ≤0.50, phosphorus P: ≤0.045, sulfur S: ≤0.03, titanium TI: (6C ~ 0.75).

409 stainless steel price
The price of 409 stainless steel is between 10 yuan and 30 yuan. It is the cheapest model (Britain and the United States). It is usually used as a car exhaust pipe, which is ferrite stainless steel (chromium steel).The price of stainless steel pipes is calculated according to specifications. The price of steel pipes of each specification is different; of course, there is a difference between seams and seamlessness.
