What is Stainless Steel 321 Round Bars?

Metcore Alloys is one of the prime and renowned manufacturers, suppliers, exporters, and stockists of qualitative Stainless Steel 321 Round Bars. The Stainless Steel 321 Round Bars are fixtures of excellent mechanical and corrosion-resistant properties, grouped in the austenitic 300 series. The alloy is closely associated with Gr 304, with an essential addition of titanium that retains stability, especially under welding processes. This addition of titanium forms titanium carbides along the weld seam and is more stable than carbide precipitates, guaranteeing superior resistance to intergranular corrosion and preventing grain boundary sensitization.

The adding of titanium also bolsters the mechanical properties of the ASTM A276 Type 321 Flat Bars, thus enabling them to be resilient under extreme temperatures, maintaining consistent yield strength and impact resistance.

Similar to Gr 304, ASTM A479 UNS S32100 Hex Bars performed very well at cryogenic temperature conditions. Elements such as chromium, nickel, manganese, and titanium are added in this alloy to ensure that the DIN 1.4541 Square Bars meet the minimum prescribed value for impact strength as well as mechanical performance properties under such temperature conditions. The main difference between AISI 321 Threaded Bars is their superior creep strength in high temperatures, where other alloys like Gr 304 would fail, thus giving way for SS 321 Bright Bars to hold its toughness and performance

The alloy also exhibits very good oxidation resistance to 816°C and higher creep and stress rupture properties than the standard grades. Bars feature good toughness at low temperatures and shall be furnished in both of the lower and higher carbon versions, with the higher carbon version available for applications requiring improved creep resistance above 1000°F. The differences in carbon provide these bars the dual certification.

The manufacturing suppliers, exporters and stockists of the AISI 321 Stainless Steel Round Bars recognize their suitability for dilute organic acids at moderate temperature and pure phosphoric acid at lower temperature and fluoride and chloride free solutions at nominal temperature. These bars are not recommended for an environment containing even with minimum concentration of sulphuric acid.

The addition of titanium in Stainless Steel 321 Round Bars prevails in industries such as construction, automotive, aerospace, and marine due to their robust corrosion resistance. These bars are resistant to cracking in case of extreme temperature fluctuations and have good fracture characteristics under stress and good weldability with or without filler materials. These bars are often machined into threaded rods, bolts, screws, and many other forms.
