Since there are many examples of different grades of stainless steel that can be used interchangeably in some of the same fields, there are always people who will ask which is better between 430 stainless steel and 304 stainless steel?

430 stainless steel has good thermal conductivity and mechanical properties, building decoration, fuel burner parts, household appliances, home appliance parts and other fields 430 stainless steel better;

304 stainless steel has strong toughness and corrosion resistance, and 304 stainless steel is better in industries that require corrosion resistance such as industry and food medical treatment.

430 stainless steel and 304 stainless steel performance comparison:

1, Corrosion resistance :

430 stainless steel contains chromium 16.00-18.00%, basically no nickel metal,

304 stainless steel contains chromium nickel metal,

so 430 stainless steel corrosion resistance is not good 304 stainless steel.

2, Stability :

430 stainless steel is ferritic form,

304 stainless steel is austenitic form,

304 stainless steel is more stable than 430 stainless steel.

3, Toughness :

304 stainless steel has strong toughness, toughness is stronger than 430 stainless steel.

4, Thermal conductivity :

430 stainless steel ferrite than 304 stainless steel austenite thermal conductivity is better,

5, Mechanical properties :

430 stainless steel added a stable chemical element titanium, weld parts mechanical properties than 304 stainless steel.

430 stainless steel application field:

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

2, in 430 steel with easy cutting performance of steel 430F, mainly used in automatic lathes, bolts and nuts.

3, add Ti or Nb in 430 steel, reduce C content into 430LX, improve the processing performance and welding performance, mainly used in hot water tanks, heating water systems, sanitary appliances, household durable appliances, bicycle flywheels and so on.

304 stainless steel application field:

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

2, 304 stainless steel has strong corrosion resistance, widely used in the production of equipment and parts requiring good comprehensive performance (corrosion resistance and formability)

Summary :

430 stainless steel and 304 stainless steel have their own advantages;

430 stainless steel has good thermal conductivity and mechanical properties, 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 industry and food Medical and other industries that need corrosion resistance, 304 stainless steel is better.
