321 Stainless Steel Plate
321 stainless steel plate is a high-quality stainless steel material that is widely used in various applications. It has excellent corrosion resistance, high temperature resistance, and good weldability. This makes it an ideal choice for use in harsh environments and industries such as chemical processing, aerospace, and power generation.
In addition to its functional properties, 321 stainless steel plate also has an attractive appearance and can be easily fabricated into various shapes and sizes. It is easy to clean, maintain, and offers long-lasting durability that makes it a cost-effective option for many projects.
Furthermore, the global demand for stainless steel is increasing year by year, and 321 stainless steel plate is expected to continue to play a significant role in the industry. This provides great opportunities for manufacturers and suppliers, and also creates more job opportunities for the workforce.
Production Specifications
- Thickness: The thickness of the sheet can range from 0.3mm to 100mm.
- Width: The sheet can be cut into different widths, ranging from 1000mm to 2500mm.
- Length: The length of the sheet can be cut to suit specific requirements, typically ranging from 2000mm to 6000mm.
- Finish: The sheet can be finished in a range of different finishes, including a polished finish, a matte finish, or a brushed finish.
- Heat treatment: AISI 321 sheet can be heat-treated to improve its mechanical properties. It can also be subjected to solution annealing at temperatures ranging from 925°C to 1010°C, followed by rapid cooling.
- Applications: AISI 321 sheet is commonly used in applications that require high-temperature resistance, such as the aerospace industry, furnace components, and exhaust systems. It is also used in the chemical and pharmaceutical industries because of its excellent corrosion resistance.
