1. Austenitic Stainless Steel Sheets
Austenitic stainless steels are the most common type, known for their excellent corrosion resistance, high ductility, and ease of fabrication. They contain high levels of chromium and nickel. Common grades include:
304 Stainless Steel: Highly versatile and widely used in kitchen equipment, chemical containers, and architectural applications.
316 Stainless Steel: Enhanced corrosion resistance due to added molybdenum, ideal for marine environments and chemical processing.
2. Ferritic Stainless Steel Sheets
Ferritic stainless steels contain lower carbon content and higher chromium levels, offering good corrosion resistance and magnetic properties. They are typically used in automotive applications, industrial equipment, and home appliances. Common grades include:
430 Stainless Steel: Known for its formability and resistance to oxidation, often used in kitchen utensils and automotive trim.
3. Martensitic Stainless Steel Sheets
Martensitic stainless steels are characterized by their high strength, hardness, and moderate corrosion resistance. They are typically used in applications requiring wear resistance and high mechanical properties. Common grades include:
410 Stainless Steel: Utilized in cutlery, surgical instruments, and valves due to its toughness and resistance to wear.
4. Duplex Stainless Steel Sheets
Duplex stainless steels combine the qualities of austenitic and ferritic steels, providing high strength, excellent corrosion resistance, and improved weldability. They are commonly used in chemical processing, oil and gas, and marine applications. Common grades include:
2205 Stainless Steel: Offers superior strength and corrosion resistance, particularly in chloride environments.
5. Precipitation-Hardening Stainless Steel Sheets
Precipitation-hardening stainless steels provide high strength and hardness through heat treatment. They are used in aerospace, defense, and other high-performance applications. Common grades include:
17-4 PH Stainless Steel: Known for its high strength and good corrosion resistance, suitable for high-stress components.
6. Surface Finishes of Stainless Steel Sheets
In addition to different grades, stainless steel sheets are available in various surface finishes, enhancing their aesthetic appeal and suitability for specific applications:
2B Finish: Smooth, reflective surface commonly used in industrial applications.
BA (Bright Annealed) Finish: Highly reflective surface used in architectural and decorative applications.
No. 4 Finish: Brushed finish providing a linear texture, often used in kitchen equipment and appliances.
