1, 304 stainless steel: excellent corrosion resistance, it contains high chromium and nickel, suitable for long-term exposure to moisture or other corrosive environments. Good high temperature resistance and mechanical properties, including high toughness. Widely used in food processing, medical equipment, chemical, aerospace, building decoration and many other fields, especially in the need for high strength and high corrosion resistance.
2, 430 stainless steel: relatively high chromium content but low nickel content, its corrosion resistance is not as good as 304 stainless steel. 430 stainless steel ferrite structure makes its thermal conductivity better than 304 stainless steel, and in some mechanical properties such as welded parts of the performance is outstanding. Used for relatively low requirements for corrosion resistance, cost control and thermal conductivity of certain requirements of the field, such as building decoration, household appliances components, kitchen equipment.
If you consider the corrosion resistance and overall strength, 304 stainless steel is usually a better choice, in the case of cost sensitivity or the need for better thermal conductivity, 430 stainless steel may be more appropriate. The selection should be based on the specific product design requirements, usage environment and budget to determine the most suitable stainless steel model.
