Stainless Steel 321 Round Bar

Neeka Tubes is a well-known manufacturer and supplier of Stainless Steel 321 Round Bars. SS 321 is a high strength material with good corrosion resistance features. It also offers excellent oxidation resistance. This makes it perfect for high temperature applications. The round shape of these bars provides equal strength and ease in the process of machining. It also has good weld ability which makes it suitable for most fabrication requirements. These Bars are available in lengths 1 to 6 meters or customisable lengths as per the client’s requirement.

SS 321 round bar (UNS S32100) contains 17-19% chromium and 9-12% nickel which provides good corrosion and heat resistant properties. It has tensile strength of 75 ksi and yield strength of 30 ksi. This provides it excellent strength and ability to endure high pressure. It has a hardness of 217 HB and elongation of 40% making it tough yet ductile. The 0.08% low carbon content means there is no formation of carbide. This composition makes it ideal for high temperatures and welding.

Advantages of Stainless Steel 321 Round Bar

  • Resistant to Wear and Tear: SS 321 round bars can handle a lot of use without getting weaker. They don’t get scratched, dented, or damaged on the surface so you can trust them even in high stress situations. This durability guarantees performance that lasts and results that are always the same.
  • Low Maintenance Requirement: These bars need very little maintenance.Their corrosion resistance and smooth surfaces reduce cleaning and repair work.This saves time and cost while keeping the bars functional for years.
  • Non-Magnetic in Nature: SS 321 is naturally non-magnetic, so it’s great for places where magnetic interference is a problem. It makes sure that things run smoothly and keeps problems from happening in sensitive industrial settings.
  • Eco-Friendly: Stainless steel 321 is fully recyclable. Choosing this material supports sustainability while delivering strong performance and helping reduce environmental impact.
  • Good Formability: These bars can be bent, machined, or shaped without cracking. This makes fabrication easier, allowing precise adaptation to different industrial and construction needs.
  • Smooth Surface Finish: The bars have a polished, even surface that reduces friction and improves aesthetics. Smooth finish also simplifies handling, installation, and regular cleaning.
