What are the standard sizes of round bars?
Round bars come in various standard sizes, typically ranging from a few millimeters to several inches in diameter. The specific sizes available may vary depending on the material and supplier.
Stainless steel 420 bars are a specific type of stainless steel alloy that belongs to the martensitic family. Stainless steel 420 is known for its high carbon content (typically around 0.15% to 0.40%) and moderate chromium content (12% to 14%), which provides it with a combination of good corrosion resistance, excellent mechanical properties, and the ability to be heat treated for increased hardness.
One of the primary features of stainless steel 420 bars is their excellent hardness and wear resistance. This makes them suitable for various applications where high strength and abrasion resistance are required. These bars are commonly used in manufacturing tools, cutlery, surgical instruments, and molds, among other industrial applications.

Stainless steel 420 bars can be heat treated to achieve different levels of hardness, making them versatile and allowing engineers to tailor the material to specific requirements. In the annealed condition, the material is relatively soft and easy to machine, but after heat treatment, it becomes much harder and more suitable for applications that demand high wear resistance.
While stainless steel 420 bars offer good corrosion resistance in mild environments, they are not as resistant to corrosion as some other stainless steel grades like the austenitic ones (e.g., 304, 316). As such, they may not be suitable for use in highly corrosive or marine environments without proper protection or maintenance.
It is essential to handle and machine stainless steel 420 bars with care, as their high carbon content can lead to brittleness if not properly treated during manufacturing processes. Additionally, post-weld heat treatment may be necessary to restore the material's toughness and ductility after welding.
