What is the difference between stainless steel steamer 304.430?

304 is austenitic stainless steel and 430 is ferritic stainless steel.
Comparison between 304 stainless steel and 430 stainless steel:
1. Corrosion resistance: 430 stainless steel contains 16.00-18.00% chromium and basically contains no nickel metal. 304 stainless steel contains more chromium and nickel metal, so the corrosion resistance of 430 stainless steel is not as good as that of 304 stainless steel.
2. Stability: 430 stainless steel is in ferrite form, 304 stainless steel is in austenitic form, and 304 stainless steel is more stable than 430 stainless steel.
3. Toughness: 304 stainless steel has strong toughness, which is stronger than 430 stainless steel.
4. Thermal conductivity: The ferrite of 430 stainless steel has better thermal conductivity than the austenite of 304 stainless steel.
5. Mechanical properties: 430 stainless steel adds the stable chemical element titanium, and the mechanical properties of the welding seam are better than 304 stainless steel.
430 stainless steel use areas:
1. 430 stainless steel is mainly used for building decoration, fuel burner components, household appliances, and home appliance components.
2. Add the easy-cutting steel grade 430F to 430 steel, which is mainly used for automatic lathes, bolts and nuts, etc.
3. Add Ti or Nb to 430 steel and reduce the C content to become 430LX, which improves the processing performance and welding performance. It is mainly used in hot water tanks, hot water supply systems, sanitary appliances, durable household appliances, bicycle flywheels, etc. .
304 stainless steel use areas:
1. 304 stainless steel has the characteristics of high temperature resistance, good processing performance and high toughness. It is widely used in industry, furniture decoration industry and food and medical industry.
2. 304 stainless steel has strong corrosion resistance and is widely used in the production of equipment and parts that require good comprehensive performance (corrosion resistance and formability).
Summary: 430 stainless steel has good thermal conductivity and mechanical properties. For building decoration, fuel burner parts, household appliances, home appliance parts and other fields, 430 stainless steel is better; 304 stainless steel has strong toughness and corrosion resistance. In industries such as industry, food and medicine that require corrosion resistance, 304 stainless steel is better.
