Cnc Machining 430 FR Stainless Steel


430 FR is a ferritic stainless steel that contains chromium and nickel. The “FR” in its name stands for “free machining,” indicating that it is designed to be easily machined using standard machining techniques. This type of stainless steel is known for its corrosion resistance, good formability, and machinability.

When CNC machining 430 FR stainless steel, the material can be easily shaped and cut into specific forms with precision. This makes it suitable for applications where both corrosion resistance and machining ease are important factors.

In summary, CNC machining is a versatile and precise manufacturing process, and 430 FR stainless steel is a type of stainless steel known for its free machining properties, making it well-suited for CNC machining applications.

The Composition Of 430 FR Stainless Steel

The Composition Of 430 FR Stainless Steel


  • Type: Stainless Steel
  • Alloy: 430 FR
  • Tolerances for 1/2″ Dia.: +.002
  • Material Cost Factor: 3
  • Machining Cost Factor: 2.7
  • General Characteristics:Corrosion resistance and high electrical resistivity

430 FR stainless steel is a ferritic stainless steel alloy, and its composition is characterized by a combination of elements that contribute to its properties. The typical composition of 430 FR stainless steel includes:

  • Chromium (Cr): Chromium is the primary alloying element in stainless steel, and it imparts corrosion resistance to the material. In the case of 430 FR, chromium content is typically around 17-18%.
  • Nickel (Ni): Nickel is added to improve corrosion resistance and enhance the material’s formability. However, the nickel content in 430 FR stainless steel is relatively low compared to austenitic stainless steels. The nickel content is typically around 0.60-1.10%.
  • Manganese (Mn): Manganese is added to improve the steel’s strength and workability. The manganese content in 430 FR is generally in the range of 1.0-1.5%.
  • Silicon (Si): Silicon is added to improve the steel’s resistance to scaling at elevated temperatures and enhance its mechanical properties. The silicon content in 430 FR stainless steel is typically around 1.0%.
  • Carbon (C): Carbon content in 430 FR stainless steel is kept relatively low to maintain good weldability and corrosion resistance. The carbon content is typically around 0.12% or lower.
  • Phosphorus (P) and Sulfur (S): These elements are controlled to low levels to ensure good machinability. The presence of sulfur is often intentionally increased to enhance the free machining characteristics of the steel.
  • Other Elements: Trace amounts of other elements, such as nitrogen and copper, may be present in 430 FR stainless steel, depending on the specific production specifications.
