Ganpat Metal manufactures and supplies Stainless Steel Hex Bars in Grade 304, 304L, 316, 316L, 321 and 347 conforming to ASTM A276 / ASME SA276 and ASTM A484. These precision hex bars are engineered for high-performance applications including high-tensile fastener manufacturing, valve bodies, precision fittings, pump components and CNC machined parts for chemical, petrochemical, pharmaceutical and marine industries.
Our stainless steel hex bars are available in cold drawn, centerless ground, solution annealed, and pickled surface conditions. Each alloy grade is carefully heat treated to achieve optimal mechanical properties, superior dimensional straightness, and exceptional corrosion resistance across diverse harsh operating environments.
With sizes ranging from 3 mm to 100 mm across flats (AF) and customized cut lengths up to 6000 mm, Ganpat Metal maintains one of the largest ready stocks of stainless steel hexagonal bars in Mumbai, ready for immediate domestic and export dispatch.
GM handles enquiries for Stainless Steel Hex Bars where buyers need to match hexagonal bar dimensions, across flats (AF) tolerances, and material grade to project drawings or purchase specifications. The supplied inventory covers precision cold drawn and hot rolled sizes beginning from 3 mm up to 100 mm across flats, with custom cut-to-length and surface finish options.
Grade selection should be based on the mechanical tensile properties, hardness, corrosion resistance, and chemical composition required by the project application. Buyers should also confirm the applicable standard specification (ASTM / ASME / EN), delivery condition (cold drawn, annealed, or quenched & tempered), inspection requirements, and documentation before finalizing an order.
