430 stainless steel is a universal 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, and it has good thermal fatigue resistance. With the addition of stabilizing element titanium, the mechanical properties of weld joints are good. 430 stainless steel is used for building decoration, fuel burner parts, household appliances and household appliances. 430F is a steel with free cutting property added to 430 steel, mainly used for automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel to reduce the content of C, which improves the processability and welding performance. It is mainly used in hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.
