420 Stainless Steel Round Bar

420 stainless steel round bar is a type of martensitic stainless steel that contains 12-14% chromium, which provides good corrosion resistance, especially in harsh environments. It also contains a minimum of 0.15% carbon, which makes it a high carbon stainless steel.

Chemical Compositions (in%):

Applications:

The high carbon content in 420 SS round bar provides good strength and hardness, making it suitable for applications such as knife blades, surgical instruments, and industrial equipment parts that require high wear resistance. However, it is not suitable for applications that require high toughness or impact resistance.

420 SS round bar can be hardened by heat treatment, such as quenching and tempering, to improve its mechanical properties. It can also be machined, welded, and polished, although it may require special techniques and tools due to its high hardness.

Overall, 420 stainless steel round bar is a versatile material that offers good corrosion resistance, high strength, and wear resistance, making it suitable for a wide range of industrial and commercial applications.
