Stainless Steel 420F Square Bar, recognized by its UNS S42020 designation, is a high-carbon martensitic
stainless steel known for its excellent strength and hardness. The inclusion of sulfur in its composition
enhances machinability, making it an ideal choice for precision machining applications. This variant of
420 stainless steel retains all the beneficial properties of its standard counterpart, with improved
machinability as a significant advantage.
Ferrobend’s Stainless Steel 420F Square Bars are manufactured with precision, adhering to strict quality
standards to ensure consistent performance. These bars offer excellent corrosion resistance in mild
environments and can be heat-treated to achieve higher levels of strength and hardness. This makes them
suitable for applications such as surgical instruments, cutlery, and tools that require high durability
and precision.
The square shape of these bars provides uniform strength and stability, making them ideal for use in
shafts, fasteners, and structural components. The material's enhanced 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 Square 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
