1, different corrosion resistance. 304 stainless steel contains high chromium and nickel, which makes it have excellent corrosion resistance, especially in oxidizing environment. Although 430 stainless steel has certain corrosion resistance, it is more susceptible to corrosion in some environments, such as chloride environment.
2. The wear resistance is different. The wear resistance of 430 stainless steel is better than that of 304 stainless steel, and it contains higher carbon element, which makes it have better hardness and wear resistance and is not easy to scratch and wear. 304 stainless steel has relatively poor wear resistance.
3. The application scenarios are different. 304 stainless steel is commonly used in food processing equipment, medical instruments and so on. , need good corrosion resistance and hygiene performance; 430 stainless steel is often used in some fields with low material requirements, such as home appliances and architectural decoration.
4. Security is different. The high chromium content in 304 stainless steel can effectively prevent the dissolution of harmful substances such as nickel and manganese in steel and reduce the harm to human body. Harmful substances such as nickel and manganese in 430 stainless steel are likely to be dissolved out, and long-term use may have an impact on human health.
5. The price is different. 304 stainless steel has high production cost, so the price is usually higher than 430 stainless steel; The relatively low cost of 430 stainless steel makes it a more economical choice in cost-sensitive applications.
