Unique Features:

321 Stainless Steel Rod is unique due to its titanium addition, which stabilizes the material and prevents carbide precipitation in welded areas, making it particularly suitable for high-temperature applications. The rod offers excellent resistance to oxidation, even in environments exposed to heat for extended periods. With superior strength at elevated temperatures, 321 maintains its integrity under thermal stresses, making it an ideal material for exhaust systems, heat exchangers, and furnace components. Its ability to resist both general and localized corrosion ensures its long-term reliability in harsh conditions.

FAQs:

1. What is the advantage of using 321 Stainless Steel Rod over standard 304 sau 316?
   • 321 Stainless Steel is stabilized with titanium, which prevents carbide precipitation during welding and provides superior high-temperature performance and resistance to thermal fatigue.
2. Can 321 Stainless Steel Rod be used in marine environments?
   • While 321 has good corrosion resistance, it is primarily designed for high-temperature applications. For marine environments, 316 stainless steel may be a better choice due to its superior resistance to saltwater corrosion.
3. What is the temperature range for 321 Stainless Steel Rod?
   • 321 Stainless Steel can withstand temperatures up to 870°C (1600°F) in continuous service and up to 900°C (1650°F) in intermittent service, making it ideal for high-heat applications.
4. Is 321 Stainless Steel Rod magnetic?
   • 321 Stainless Steel is generally non-magnetic in its annealed state, but it can become slightly magnetic if cold-worked.
5. Can 321 Stainless Steel Rod be welded?
   • Yes, 321 is highly weldable, and the titanium stabilizing element prevents the formation of carbide precipitates, ensuring that the welded joints maintain excellent corrosion resistance.
6. What certifications are available with 321 Stainless Steel Rod?
   • Our 321 Stainless Steel Rod complies with ASTM A276 and ASTM A240 standards, and mill test certificates can be provided upon request.
