Stainless Steel 430F Square Bar, recognized by its UNS S43020 designation, is a ferritic stainless steel
well-known for its superior machinability and moderate corrosion resistance. This alloy is specially
formulated to offer enhanced machinability, making it an excellent choice for precision machining
applications. The inclusion of sulfur in its composition improves its machinability without significantly
affecting its corrosion resistance, making it suitable for various industrial uses.
Ferrobend’s Stainless Steel 430F Square Bars are meticulously manufactured to meet stringent quality
standards, ensuring consistent performance and reliability. These bars are characterized by their high
strength and good corrosion resistance in mildly corrosive environments, making them ideal for use in
fasteners, gears, shafts, and other components that require precision machining and high durability.
The square bar shape provides uniform strength and stability, making it perfect for applications in
mechanical assemblies and high-stress installations. The material's excellent machinability allows for
easy fabrication into complex shapes and components, meeting the specific requirements of various
engineering applications. Additionally, the ferritic structure provides good resistance to stress
corrosion cracking and oxidation, further enhancing its suitability for demanding industrial tasks.
