Stainless Steel 441 is one of the most used ferritic stainless steel due to its ability to withstand oxidation and corrosion, hence suitable for use in places that need to be durable and attractive. Selectively used for their high performance, reasonable price and easy to fabricate, Stainless Steel 441 sheets and plates are made from a combination of chromium, iron, columbium (niobium) and a small amount of titanium to increase its resistance to intergranular corrosion and oxidation at high temperature. This unique combination creates several desirable characteristics and uses in many industries.
Key Properties of SS 441 Sheets & Plates
441 Stainless Steel sheets and plates is notable for several unique properties:
- High Oxidation Resistance: The SS 441 sheet does not undergo oxidation until temperatures of approximately 850°C and therefore can be used in high temperatures.
- Corrosion Resistance: With a high chromium content (about 18%), SS 441 plate is known for its exceptional corrosion resistance, especially against localized corrosion. This makes it ideal for areas exposed to moisture and chemicals.
- Thermal Stability: The presence of columbium and titanium in the alloy gives 441 Stainless Steel plates great stability and reduces grain growth at high temperatures for long periods.
- Magnetic Properties: The SS 441 sheet is also magnetic unlike austenitic stainless steels which can be useful in applications that need magnetic response.
- Formability and Weldability: It has excellent formability, which makes sheets & plates suitable for fabrication and machining into different forms needed in different applications. Also, it has good weldability, thus increasing its application in production processes.
Applications of Stainless Steel 441 Sheets & Plates
Stainless Steel 441 sheet is used in many industries due to its features such as high corrosion resistance, strength and heat resistance.
- Automotive Industry
- Exhaust Systems: Due to high heat resistance and corrosion, SS 441 plate is used in automotive exhaust systems where components frequently experience high temperatures and corrosive emissions.
