VIP ferromet is an esteemed manufacturer, distributor, and supplier of Stainless Steel 321 grade Bars. SS 321H grade Round Bar is known as an austenitic steel bar. The lower carbon content of grade 321 bar reduces its high-temperature resistance compared to 321H. Grade 321 contains about 0.08 carbon and grade 321H contains about 0.060.10 percent carbon content in their overall chemical composition. Grade 321H bar is a modification of grade 321 bar with higher carbon content, benefiting from better high-temperature resistance. These quality bars are designed for pitting and crevice corrosion in environments with hot chlorides and stress corrosion cracking above approximately 60°C. 321H grade bar has extreme hot strength and is precisely suitable for high-temperature structural applications. Some of the key features of 321 & 321H grades are exceptional impact strength, toughness, formability, structural accuracy, and metallurgical properties. In addition to these features, they also possess properties such as excellent weldability through standard casting methods. Titanium addition in this grade 321 bar eliminates the formation of chromium carbides at the grain boundaries by tying up the carbon and nitrogen as titanium carbides or nitrides.

SS 321 grade Bars cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working. Grade 321 bar has a low carbon content which makes steel an ideal raw material. Mostly steel contains a large amount of nickel and chromium. Aircraft exhaust manifolds, Expansion joints, Furnace parts, textile, fabrication, construction, cement, shipbuilding, Heating element tubing, Heat Exchangers, Welded screens for elevated-temperature mineral processing, and Spiral Welded tube are some of the major applications of these grade 321H bars in mainstream Industries. The mixture of nickel and chromium in these grade bars makes them susceptible to warmth treatment. VIP ferromet offers pure Stainless Steel 321H grade Bars and other similar range products at competitive market rates to our diversified base of customers.
