304Stainless steel plate

304 Stainless Steel Plate (Export Grade)
Product Overview
304 stainless steel plate is the most widely used austenitic stainless steel in global markets, renowned for its balanced performance, cost-effectiveness, and versatility. Compliant with international standards including ASTM A240, JIS G4305, EN 1.4301, and GB/T 3280, it serves as the preferred material for cross-border projects in construction, industrial manufacturing, food processing, and medical equipment industries.
Core Advantages

- Superior Corrosion Resistance: Exhibits excellent resistance to atmospheric oxidation, fresh water, weak acids (acetic acid, citric acid), weak alkalis, and organic compounds. Suitable for outdoor use, coastal environments, and food contact applications without rusting or discoloration.
- Exceptional Processability: Features excellent formability, weldability (compatible with TIG, MIG, and arc welding), and machinability. Can be easily cut, bent, stamped, deep-drawn, and polished to meet custom component requirements.
- Stable Mechanical Properties: Maintains high tensile strength and ductility at room temperature (tensile strength ≥515MPa, elongation ≥40%), ensuring structural stability in long-term use. Non-magnetic in annealed state, with no magnetic deviation after processing.
- Food-Grade Safety: Meets FDA and EU food contact material standards (EC 1935/2004), non-toxic and odorless, making it ideal for food processing equipment, kitchenware, and beverage pipelines.
- Durable & Low Maintenance: Smooth surface texture resists dirt accumulation; no need for regular anti-corrosion treatment, reducing long-term operational costs for overseas clients.
