Technical Specifications
Product Overview
304 Stainless Steel Plate is manufactured from premium grade 304 austenitic stainless steel, providing excellent corrosion resistance, formability, and weldability. This versatile plate material is ideal for a wide range of industrial, architectural, and food processing applications.
Key Features:
- Excellent corrosion resistance in most environments
- Superior formability and deep drawing capabilities
- Non-magnetic in annealed condition
- FDA approved for food contact applications
- Easy to clean and maintain hygienic surfaces
- Good weldability with all standard welding methods
Manufacturing Process: Hot rolled and cold rolled using advanced mill technology, followed by annealing and pickling to achieve optimal mechanical properties and surface finish.
Applications: Kitchen equipment, food processing machinery, chemical processing equipment, pharmaceutical equipment, architectural panels, decorative applications, pressure vessels, and general fabrication projects requiring corrosion resistance.
