Ganpat Metal manufactures and supplies certified Alloy Steel F11 / WP11 (1.25% Cr 0.5% Mo) Hex Bars conforming to ASTM A182 F11 Class 2 / ASME SA182. Alloy Steel F11 Class 2 (1.25Cr-0.5Mo) is the industry standard chrome-moly grade for moderate to elevated temperature boiler headers, steam lines, and heat exchangers up to 550°C. It offers outstanding weldability and creep strength.
Our ASTM A182 F11 hexagonal bars are supplied in cold drawn, centerless turned, annealed and pickled, or precipitation hardened condition depending on standard specifications. They exhibit superior surface smoothness, precise across-flats dimensions, excellent straightness, and uniform metallurgical grain structure tailored for CNC machined components and high-tensile fastener manufacturing.
We maintain extensive inventories in sizes from 3 mm to 100 mm across flats, ready for immediate dispatch from our Mumbai central warehouse with EN 10204 Type 3.1 Mill Test Certificates and optional third-party inspection.
GM handles enquiries for ASTM A182 F11 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.
