430 Stainless Steel Sheets and Plates Supplier

• Chemical composition: 430 stainless steel sheet contains 16% to 18% chromium and trace amounts of nickel, manganese, and other elements, while 304 stainless steel sheet contains around 18% chromium, around 8% nickel, and small amounts of carbon and other elements.
• Physical properties: 430 stainless steel sheet is harder, more brittle, and more prone to wear than 304 stainless steel sheet. However, its corrosion resistance is relatively poor compared to 304 stainless steel sheet.
• Stability: 304 stainless steel sheet is in the austenite phase, making it more stable than 430 stainless steel sheet.
• Toughness: 304 stainless steel sheet has stronger toughness and is less prone to fracture than 430 stainless steel sheet.
• Thermal conductivity: The ferritic structure of 430 stainless steel sheet gives it better thermal conductivity than the austenitic structure of 304 stainless steel sheet.

• Chemical composition: 430 stainless steel sheet primarily contains chromium and does not contain or contains only trace amounts of nickel, while 316 stainless steel sheet contains higher levels of chromium and nickel, with the addition of molybdenum. This makes the chemical composition of 316 stainless steel sheet more complex.
• Corrosion resistance: Due to the addition of molybdenum, 316 stainless steel sheet exhibits better corrosion resistance than 430 stainless steel sheet, particularly in seawater and other corrosive environments. While 430 stainless steel sheet also has some corrosion resistance, it may not perform as well as 316 stainless steel sheet in certain harsh environments.
• Cost: Generally, 316 stainless steel sheet has a higher cost compared to 430 stainless steel sheet due to its higher alloy content and more complex production process. On the other hand, 430 stainless steel sheet is relatively cheaper and suitable for applications where cost is a significant factor.

No, 430 stainless steel sheet does not meet food-grade standards. Although it is a type of stainless steel material, it does not comply with the requirements of the national standard GB 9684 and therefore cannot be certified as food-grade stainless steel. When selecting food-grade stainless steel, it is recommended to use materials such as 304 or 316 that comply with national standards.

The service life of 430 stainless steel plate depends on a variety of factors, such as the use environment, operation methods, maintenance and other factors. In general, the service life of 430 stainless steel plate is relatively short, usually about 5-10 years, but the specific life expectancy needs to be assessed on a case-by-case basis. In the process of use, regular inspection, cleaning and maintenance can extend the service life of 430 stainless steel plate.

• Maintain dryness: Avoid prolonged exposure to moist environments to reduce the possibility of corrosion.
• Avoid scratching: Prevent contact with sharp objects during use to minimize surface scratches and damage.
• Regular cleaning: Clean the surface regularly with mild detergent and a soft cloth to remove stains and dust.
• Avoid exposure to direct sunlight: Try to avoid prolonged exposure to strong sunlight to prevent damage from UV radiation.
• Proper storage: When storing, keep the area dry, well-ventilated, and avoid contact with chemical substances.
