Stainless Steel 321 Welding Rod Manufacturer, Stainless Steel 321 Welding Rod, Stainless Steel 321 Welding Rod in India, Stainless Steel 321 Welding Rod in Mumbai
Labdhi Metals is a well-established manufacturer, stockist, and exporter of high-quality Stainless Steel 321 Welding Rods, engineered for critical welding applications in high-temperature and corrosive environments. SS 321 is a titanium-stabilized austenitic stainless steel designed to resist intergranular corrosion after welding and exposure to elevated temperatures. Labdhi Metals provides SS 321 welding rods that meet international welding standards and are widely used in piping, fabrication, and structural work across industries.
The welding rods made from Stainless Steel 321 offer excellent resistance to oxidation and scaling at temperatures up to 870°C. Due to the presence of titanium, these rods effectively prevent carbide precipitation during the welding process, which enhances the corrosion resistance of the weld area. These rods are suitable for welding SS 321 base materials as well as other stabilized and non-stabilized austenitic stainless steels used in furnace components, exhaust systems, heat exchangers, and chemical tanks.
Labdhi Metals produces SS 321 welding rods in multiple forms, such as TIG (GTAW), MIG (GMAW), and SMAW (Shielded Metal Arc Welding) types. The rods are available in various diameters and lengths, packaged in spools, cut-lengths, and vacuum-sealed boxes, depending on the welding application. Each batch undergoes thorough quality inspection, including radiographic testing, bend tests, and chemical analysis, ensuring optimum weld quality and performance.
As a reliable stockist, Labdhi Metals maintains an extensive inventory of SS 321 welding rods to ensure prompt delivery for urgent domestic and international orders. The company exports its products to over 20 countries including the USA, Germany, UAE, Saudi Arabia, South Africa, and Southeast Asia. Labdhi Metals supplies welding consumables with complete traceability and documentation including Mill Test Certificates (MTCs) and third-party inspection reports.
