The difference between 430 VS 304 stainless steel plate?

430 and 304 stainless steel plates are common stainless steel materials, and there are several main differences between them:

1. Chemical composition: 430 stainless steel contains over 17% chromium and lower nickel content (usually less than 1%), while 304 stainless steel contains 18% chromium and 8% nickel. This makes 304 stainless steel more resistant to corrosion and oxidation.

2. Corrosion resistance: 304 stainless steel has better corrosion resistance, especially in chlorine containing media or acidic environments. In contrast, 430 stainless steel may corrode in some harsh environments.

3. Magnetism: 430 stainless steel is magnetic, while 304 stainless steel is usually non-magnetic. This magnetic property can be used to distinguish between these two materials.

4. Application areas: Due to the excellent corrosion resistance and mechanical properties of 304 stainless steel, it is commonly used in food processing equipment, chemical equipment, building decoration, etc; 430 stainless steel is usually used for general purposes such as household appliances, car exhaust pipes, etc., and is relatively economical in price. The choice of which one to use depends on specific needs and budget considerations.
