1. Corrosion resistance: 430 stainless steel contains 16.00-18.00% chromium, basically 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. Mechanical properties: 430 stainless steel is added with a stable chemical element titanium, and the mechanical properties of the weld are better than 304 stainless steel;
3. Toughness: 304 stainless steel has strong toughness, which is stronger than 430 stainless steel;
4. Stable performance: 430 stainless steel is in ferrite form, 304 stainless steel is in austenitic form, 304 stainless steel is more stable than 430 stainless steel;
5. Thermal conductivity: The ferrite of 430 stainless steel has better thermal conductivity than the austenite of 304 stainless steel.
1. 430 stainless steel is mainly used for architectural decoration, fuel burner parts, household appliances, and home appliance parts;
2. The steel grade 430F with free cutting performance is added to the 430 steel, which is mainly used for automatic lathes, bolts and nuts, etc.;
3. Add Ti or Nb to 430 steel, reduce the C content to 430LX, improve the processing performance and welding performance, mainly used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc. .
