409Ni Stainless Steel Strips/ Coils- SCALE STEEL.

​409Ni stainless steel is a ferritic stainless steel with a chemical composition of 0.03% carbon, 10.5%-11.7% chromium, 0.5% nickel, and <1% manganese. It also contains small amounts of silicon, phosphorus, sulfur, and nitrogen. The presence of nickel in 409Ni stainless steel enhances its corrosion resistance, especially in environments that contain chlorides such as saltwater or acidic gases.

This stainless steel has good weldability, formability, and ductility, making it suitable for various applications in industries such as automotive, construction, and food processing. One of its notable features is its high temperature resistance, which allows it to retain good mechanical properties and corrosion resistance even under high temperatures.

The mechanical properties of 409Ni stainless steel include a tensile strength of 380-550 MPa, yield strength of 195-300 MPa, and elongation of 20-30%. Its hardness ranges from 80-90 HRB.

Some common applications of 409Ni stainless steel include exhaust systems, catalytic converters, mufflers, heat exchangers, and automotive trim and molding. It is also used in chemical processing equipment, building structures, and food processing equipment.

In summary, 409Ni stainless steel is a robust and versatile material that offers good mechanical properties, high temperature resistance, and effective corrosion resistance in harsh environments with chloride ion exposure. Its broad range of applications makes it a popular choice for many industries.
