430 stainless steel is a general-purpose steel with good corrosion resistance. It has better thermal conductivity than austenite, a smaller thermal expansion coefficient than austenite, heat fatigue resistance, addition of stabilizing element titanium, and good mechanical properties at the weld. 430 stainless steel is used for building decoration, fuel burner parts, household appliances, and home appliance parts. 430F is a steel grade with free-cutting performance added to 430 steel. It is mainly used for automatic lathes, bolts and nuts.

Steel 430 is used in lots of decorative applications where chances of stress corrosion cracking are high. Common applications are

  • Dish Washer Liners
  • Refrigerator Cabinet Panels
  • Stove Trim Rings
  • Fasteners
  • Fuel Linings


430 stainless steel is ferritic steel containing chromium as major alloying elements and belongs to the category of non-hardenable steel. This steel grade provides an excellent combination of corrosion resistance and practical mechanical properties. Common Applications of this steel are Automatic Screw machines, Dishwasher linings, and lashing wires.

430 stainless steel is considered easily machineable as compared to 300 series of Stainless steel. The reason for easy machining is high elastic modulus. High elastic modulus material does not stretch or bend easily, resulting in better machining.

Grade 430 steel belongs to the class of ferritic steels and all ferritic grades have excellent corrosion resistance (stress-corrosion). They are resistant to several chemicals, organic and nitric acids. Corrosion resistance further levels up if this steel is used in polished condition. In the case of pitting corrosion resistance, it is comparable to 304 steel.

Food grade means still must have high crossing resistance, resistance against stress corrosion cracking, organic and nitric acids. All these qualities are present in 430 steel due to very high chromium content making it one of the best food-grade steel in the market.

430 is the best food-grade material with magnetic characteristics. It has good corrosion resistance with practical sheet bending ability. This steel can be used in the presence of strong acids and also at high temperatures like 800 .

Stainless steel 430 is made of 16% Chromium, 0.1% Carbon, 1% Manganese, 1% silicon and 0.03% sulfur.

430 stainless is ferritic steel while 316 steel is austenitic steel. The ferritic structure is magnetic while the austenitic structure is non-magnetic. Due to the ferritic structure of 430 steel, It is attracted to a magnet.

304 and 430 are different in terms of structure. 304 steel is austenitic while 430 steel is ferritic. Due to this 304 is non-magnetic while 430 is magnetic. Due to higher chromium content in 430 as compared to 304, it can be used in food processing applications.
