Incoloy 825 / Aleación 825 Flanges – ASTM B564 UNS N08825
Aleación forjada 825 flange solutions for selected acid, pollution-control, oil-and-gas and chemical-process systems requiring UNS N08825.
Quick engineering answer
Incoloy 825 and Alloy 825 are established names for UNS N08825, a nickel-iron-chromium alloy containing molybdenum and copper. For forged flanges, the procurement identity is ASTM B564 UNS N08825. “Inconel 825” appears in searches, but it is not the preferred grade name.
Product specification
| Material | ASTM B564 UNS N08825 aleación de níquel-hierro-cromo |
|---|---|
| Available forms | cuello de soldadura, ciego, deslizarse, soldadura de encaje, roscado, junta de regazo, orifice and drawing-specific flanges where permitted |
| Dimensional standards | ASME B16.5; ASME B16.47 for applicable large diameters; EN 1092-1 or approved drawings on request |
| Clases de presión | Clase 150, 300, 400, 600, 900, 1500 y 2500 within the selected standard, material group and size limits |

| Documentación | EN 10204 3.1 MTC, trazabilidad del número de calor, dimensional report and ordered inspection records |
Pressure-temperature ratings depend on the governing code, flange standard edition, grupo de materiales, tamaño y clase. Confirm the complete project specification before ordering.
Grade and terminology check
| Preferred page name | Incoloy 825 / Aleación 825 Bridas | Supports both recognized purchasing terms |
|---|---|---|
| Formal material identity | ASTM B564 UNS N08825 | EN 2.4858 is a commonly cross-referenced designation |
| Common search variant | Inconel 825 bridas | Clarify the terminology instead of using it as the primary product name |
Selección de materiales
Aleación 825 is selected for useful resistance in several reducing and oxidizing acid environments, but service suitability is conditional. Química de los medios, acid concentration, cloruros, impurezas, aireación, temperatura, crevices and welding history require review.
Matching-material note: Match the exact UNS N08825 product-form specification for pipe, fittings and other adjoining components. A common alloy family name does not replace the standard required for each product form.
Quality controls available
- PMI with heat-number traceability
- EN 10204 3.1 certificado de materiales
- Intergranular, corrosion or NDE testing when specified
- Dimensiones, facing finish and visual inspection
Aplicaciones típicas
Applications are selection cues, not blanket approvals. Medios de proceso, presión, temperatura, corrosion data, fatigue, fabrication and code requirements govern final suitability.
Standards hierarchy
Información requerida para la cotización
Provide the material grade, tipo de brida, estándar y edición, NPS o DN, pressure class or PN rating, tabla de tuberías o diámetro exacto, facing and finish, cantidad, destino de entrega, tratamiento térmico, ECM, pruebas, certification and third-party inspection requirements.
Preguntas frecuentes
Should buyers specify Inconel 825 or Incoloy 825?
Use Incoloy 825 or the generic name Alloy 825, and place ASTM B564 UNS N08825 on the purchase order. This avoids ambiguity regardless of the commercial trade name used in a search.
Which flange styles are available?
Depending on size, clase y estándar, supply can include weld neck, ciego, deslizarse, socket-weld, roscado, lap-joint, orifice and drawing-specific flanges.
What documentation can be supplied?
La documentación típica incluye un EN 10204 3.1 MTC, heat traceability and dimensional report. PMI, ECM, corrosion testing and third-party inspection can be added when specified before manufacture.
Request a specification review and quotation
Send the complete RFQ or piping material specification. SASA FLANGE will review grade identity, dimensiones, frente a, inspection and documentation before production.
