Harshita Stainless, a well-known Dubai-based manufacturer and supplier, is famous for supplying high–quality stainless steel products, such as high-performance Stainless Steel 348 Flanges. Priced to satisfy the stringent requirements of chemical processing, petrochemical, and pharmaceutical industries, these flanges have outstanding resistance to high temperatures, oxidation, and corrosive substances. With emphasis on precision engineering, quality assurance, and prompt delivery, Harshita Stainless provides reliable solutions for mission-critical operations. No matter your requirements in Delhi or other industrial centers, Harshita Stainless provides trustworthy stainless steel flange products for long-term viability and process efficacy.
Stainless Steel 348 Flanges are made of a niobium-stabilized austenitic stainless steel alloy consisting mainly of 18–20% chromium, 9–12% nickel, and iron, with the addition of niobium in proportions approximately 10 times greater than the carbon content to avoid carbide precipitation. It improves resistance to intergranular corrosion, particularly following welding or long-term high-temperature exposure. Mechanical properties are tensile strength of 515–690 MPa, yield strength of 205 MPa, and elongation of 40% in 50 mm. The flanges have good weldability, formability, and heat stability and are suitable for harsh operational conditions.

Stainless Steel 348 Flanges are widely applied in high-temperature and corrosive applications, mainly in the aerospace, chemical processing, petrochemical, and power industries. Their resistance to oxidation and intergranular corrosion stability render them effective for application in heat exchangers, boilers, reactors, and other systems that process aggressive chemicals at high temperatures. Stabilization with niobium (columbium) resists sensitization during welding, which improves performance in fabrication-intensive applications. Because of their high mechanical strength and corrosion resistance against sulfuric and phosphoric acids, SS 348 flanges are also relied upon in fertilizer plants, refineries, and steam piping systems for dependable long-term operation.
