Alloy Steel Flanges for Food Processing — ASTM A182

ASTM A182 is the standard specification for forged or rolled alloy and stainless steel pipe flanges, fittings, and valves intended for high-temperature service. In food processing, this standard ensures the material meets defined chemical composition and mechanical property requirements, making flanges suitable for high-pressure, high-temperature, and chemically aggressive environments common in food and beverage production.

Common ASTM A182 grades for food processing include F304, F316, and F316L stainless steels, which offer excellent corrosion resistance to cleaning chemicals and acidic food products. Duplex grades like F51 (2205) are also used where higher strength and chloride resistance are needed. MTS Forge can produce flanges in a range of grades — contact us to discuss which best suits your application.

MTS Forge manufactures a variety of flange types — including weld neck, slip-on, blind, socket weld, and threaded configurations — up to 14 inches in size. Custom configurations beyond standard offerings are also available. Our in-house tooling design capability allows us to accommodate non-standard geometries for specialized food processing equipment.

Yes. Every flange produced at MTS Forge is supported by a comprehensive Quality Assurance Program that provides complete traceability from raw material receipt through forging, heat treatment, machining, and final inspection. Material test reports (MTRs) and certifications are provided with each order, meeting the documentation requirements of food processing procurement and regulatory compliance teams.

MTS Forge performs in-house normalizing heat treatment, which heats the forged flange above its upper critical temperature and allows controlled air cooling. This refines the grain structure, relieves internal forging stresses, and improves tensile strength, toughness, and machinability — producing flanges with uniform mechanical properties consistent with ASTM A182 requirements for demanding service conditions.

Absolutely. Custom forging is a core capability at MTS Forge. Our team can produce flanges to exact customer-supplied drawings and specifications, including non-standard bore sizes, face types, pressure classes, and material grades. With an extensive in-house tooling inventory and the ability to design new tooling, we can accommodate unique food processing equipment requirements efficiently and at competitive cost.

MTS Forge's Quality Assurance Program is certified to Mil I 45208, NCA 3800, and Mil Q9858 — standards that demand rigorous inspection, documentation, and process control. These certifications reflect the company's long-standing commitment to manufacturing precision and reliability, and provide the quality framework that supports ASTM A182 flange production for critical industries including food processing, nuclear, aerospace, and defense.

MTS Forge aims to respond to quote requests promptly. To generate an accurate quote, please provide the flange type, nominal pipe size and pressure class, ASTM A182 grade required, quantity needed, any applicable drawings or dimensional standards (e.g., ASME B16.5), and delivery timeline. The more detail you can share upfront, the faster our team can prepare a precise and competitive proposal.
