Labdhi Metals is a recognized manufacturer, stockist, and exporter of superior-quality Stainless Steel 347 Strip, Sheet & Plate, delivering corrosion-resistant and heat-stable flat products to various industries across the globe. Stainless Steel 347 is a niobium (columbium)-stabilized austenitic stainless steel, specifically designed to offer enhanced resistance to intergranular corrosion and improved mechanical strength at elevated temperatures. Labdhi Metals manufactures these products using state-of-the-art technology, ensuring international quality standards and dimensional precision.
SS 347 flat products are ideal for applications involving continuous exposure to high temperatures and frequent thermal cycling, such as in furnace components, heat exchangers, aerospace parts, exhaust systems, and chemical processing units. The addition of niobium helps prevent carbide precipitation during welding or thermal exposure, making the material more reliable in welded structures. Labdhi Metals offers SS 347 in a variety of thicknesses, widths, lengths, and surface finishes like 2B, No.4, BA, and mirror to meet diverse industrial requirements.
Labdhi Metals produces SS 347 Strips, Sheets & Plates in both hot-rolled and cold-rolled conditions, with the ability to provide custom dimensions as per project specifications. These products comply with standards such as ASTM A240 and ASME SA240, ensuring compatibility with global engineering and construction norms. Labdhi also offers value-added services like shearing, cutting, polishing, and surface coating, catering to sectors like petrochemicals, refineries, marine, pharmaceuticals, and thermal power plants.
As a prominent stockist, Labdhi Metals maintains a large inventory of SS 347 flat products, ensuring immediate availability for both domestic and export markets. The company exports its Stainless Steel 347 sheets, plates, and strips to major international markets, including the USA, Germany, UAE, Saudi Arabia, South Africa, and Southeast Asia. All products are delivered with Mill Test Certificates (MTCs), third-party inspection documentation, and full traceability.
