430 stainless steel is a general steel with good corrosion resistance. Its thermal conductivity is better than that of austenite. Its coefficient of thermal expansion is smaller than that of austenite. It has good thermal fatigue resistance. The mechanical properties of weld seam are better when adding stabilized element titanium. 430 stainless steel is used for building decoration, fuel burner parts, household appliances and household appliances. 430F is a kind of steel with free cutting property added to 430 steel. It is mainly used for automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel, reduces C content, improves processing performance and welding performance. It is mainly used in hot water tank, heating water system, sanitary appliances, household durable appliances, bicycle flywheel and so on.

 

Because of its chromium content, it is also called 18/0 or 18-0. Compared with 18/8 and 18/10, the chromium content is slightly less and the hardness decreases accordingly.
