Stainless Steel 321 Round bar are the basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

If you want to buy Stainless Steel 321 Bar in India, Saudi Arabia, South Africa, Malaysia, Indonesia, Kuwait, UAE, Korea, Russia or anywhere in the world here are few tips to buy quality products on time:
Its about one of our client in Abu Dhabi city, we have exported 1 Ton Hot rolled barto them in Oct, 2016, just before Diwali (India’s main Hindu festival) along with Mill certificate & third party documents, but the project chief engineer required 1 ton more Cold drawn bar on urgent basis, in our factory 99% workers & staff gone for Diwali vacation, even i was also out of town to celebrate Diwali, but when our client’s requested me that its a emergency so i immediately took a flight on the auspicious day of Diwali morning & arranged to export the material on the same day, & then i went back & celebrated Diwali at my home happily. My client was so surprised to see that because in India no one was ready to ship the materials in whole October Due to Diwali vacation, he says me thanks & sent me a special gift, i was feeling very happy that day because we works 300 days out of 365 Days but after working hard in difficult circumstances you will more enjoy in your holidays.

Equivalent to Grade 304 in the annealed condition, and superior if a weldment in these grades has not been post-weld annealed or if the application involves service in the 425-900°C range. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C.
Good oxidation resistance in intermittent service to 900°C and in continuous service to 925°C. These grades perform well in the 425-900°C range, and particularly where subsequent aqueous corrosive conditions are present. 321H has higher hot strength, and is particularly suitable for high temperature structural applications.
Solution Treatment (Annealing) - heat to 950-1120°C and cool rapidly for maximum corrosion resistance.
Stabilising - heat to 870-900°C for 1 hour per 25mm of thickness and air cool. Stabilisation is recommended for most severe service conditions (above 425°C) and particularly for material annealed at the upper side of the annealing temperature range.
Stress Relief - Heat to 700°C for 1 to 2 hours and air cool.
These grades cannot be hardened by thermal treatment.
Excellent weldability by all standard fusion methods, both with and without filler metals. AS 1554.6 pre-qualifies welding of 321 and 347 with Grade 347 rods or electrodes; high silicon version of 347 is also pre-qualified for welding of 321.
Typical applications include:
• Aircraft exhaust manifolds
• Expansion joints
• Furnace parts
• Heating element tubing
• Heat Exchangers
• Woven or welded screens for high temperature mineral processing
• Spiral Welded tube for burner pipes and flues
