Is 304 or 430 stainless steel bar better?

There are many members in the stainless steel family. In daily life, different types have different applications. Many people get confused when faced with choices. Let us find out which one is better, 304 or 430 stainless steel bar.

The difference between 304 and 430 stainless steel bars

304 is austenitic stainless steel, and 430 is ferritic stainless steel.

1. Corrosion resistance: 430 stainless steel bar contains 16.00-18.00% chromium and does not contain nickel metal. 304 stainless steel bar contains more chromium and nickel metals, so 430 stainless steel has no better corrosion resistance than 304 stainless steel.

2. Stable performance: 430 stainless steel is of ferrite form, 304 stainless steel is of austenitic form, 304 stainless steel is more stable than 430 stainless steel.

3. Toughness: 304 stainless steel has strong toughness, which is stronger than that of 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 is added with a stable chemical element titanium, and the mechanical properties of the weld are better than 304 stainless steel.

 

430 stainless steel application field

1. 430 stainless steel bar is mainly used for building decoration, fuel burner parts, household appliances, and home appliance parts.

2. The 430F steel grade with free-cutting performance is added to the 430 steel, which is mainly used for automatic lathes, bolts, and nuts.

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 for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.

 

304 stainless steel application field

1. 304 stainless steel bar has the characteristics of high-temperature resistance, good processing performance, and high toughness. It is widely used in the industry and furniture decoration industry and the food and medical industry.

2. 304 stainless steel bar has strong corrosion resistance and is widely used in the production of equipment and parts that require good comprehensive performance (corrosion resistance and formability).

 

430 stainless steel bar has better thermal conductivity and mechanical properties. 430 stainless steel is better for architectural decoration, fuel burner parts, household appliances, home appliance parts, etc.; 304 stainless steel bar has strong toughness and corrosion resistance, and is used in industrial and For industries that require corrosion resistance, such as food and medical, 304 stainless steel bar is better.
