Home / Threaded Bar
Stainless Steel 420F Threaded Bar, known by its UNS S42020 designation, is a martensitic
stainless steel offering high strength and hardness. This alloy is enhanced with sulfur to
improve its machinability, making it a preferred choice for precision machining
applications. The 420F variant maintains the excellent mechanical properties of standard 420
stainless steel while providing better machinability, making it suitable for a wide range of
industrial applications.
Ferrobend's Stainless Steel 420F Threaded Bars are manufactured to meet stringent quality
standards, ensuring consistent performance and reliability. These bars exhibit excellent
corrosion resistance in mild environments and can be hardened through heat treatment to
achieve higher strength and hardness levels. This makes them ideal for applications such as
fasteners, shafts, and structural components that require high durability and precision.
The threaded design ensures secure and reliable fastening, making these bars perfect for use
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. The alloy's ability to maintain
high strength and hardness after heat treatment further enhances its suitability for
demanding industrial tasks.
Choosing Ferrobend's Stainless Steel 420F Threaded Bars guarantees a robust and reliable
solution for your industrial needs. Our commitment to quality and customer satisfaction
ensures that you receive materials that perform exceptionally well, reducing maintenance
costs and downtime. With Ferrobend, you can trust that our stainless steel products will
