Супер Дуплекс F53 & F55 Flanges – UNS S32750 / S32760
Страница сравнения спецификаций и поставок двух различных марок супердуплексных кованых фланцев.. It helps buyers identify the correct ASTM grade and UNS number before requesting manufacture.
Quick engineering answer
ASTM A182 F53 and F55 are separate super duplex forging grades. F53 corresponds to UNS S32750, while F55 corresponds to UNS S32760. They share high strength and strong localized-corrosion resistance, but their chemistry and project approvals differ, so they must not be substituted automatically.
Product specification
| Материал | ASTM A182 F53 / UNS S32750 и ASTM A182 F55 / UNS S32760 |
|---|---|
| Available forms | Приварная горловина, слепой, без шнуровки, раструбная сварка, резьбовой, коленный сустав, 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 |
| Pressure classes | Сорт 150, 300, 400, 600, 900, 1500 и 2500 within the selected standard, material group and size limits |
| Облицовка | Поднятое лицо (РФ), Кольцевое соединение типа (РТЖ), Плоское Лицо (ФФ) where permitted, or drawing-specific facing |
| Документация | EN 10204 3.1 МТС, прослеживаемость плавки, dimensional report and ordered inspection records |
Pressure-temperature ratings depend on the governing code, flange standard edition, группа материалов, размер и класс. Confirm the complete project specification before ordering.
Grade and terminology check
| Procurement grade | ASTM A182 F53 | ASTM A182 F55 |

| Обозначение США | S32750 | S32760 |
| Common EN number | 1.4410 | 1.4501 |
| Правило выбора | Use when the approved project specification calls for F53/S32750 | Use when the approved project specification calls for F55/S32760 |
Выбор материала
Use the exact grade stated in the piping material specification. F55 includes intentional copper and tungsten additions compared with F53, but material selection still depends on the process environment, температура, fabrication route and project qualification—not on a simple higher-grade assumption.
Matching-material note: Coordinate forged flanges with pipe and fittings in the exact approved UNS grade. Confirm solution heat treatment, phase balance, welding controls and any ASTM A923, ferrite or project-specific corrosion-test requirements.
Quality controls available
- PMI and heat-number traceability
- Ferrite or phase-balance verification when ordered
- ASTM A923 or project corrosion testing when specified
- ЮТ, PT and dimensional inspection to the ordered scope
Типичные применения
Applications are selection cues, not blanket approvals. Process media, давление, температура, corrosion data, fatigue, fabrication and code requirements govern final suitability.

Информация, необходимая для предложения
Provide the material grade, тип фланца, стандарт и издание, НПС или DN, pressure class or PN rating, график труб или точный диаметр отверстия, facing and finish, количество, delivery destination, термическая обработка, ОСП, тестирование, certification and third-party inspection requirements.
Часто задаваемые вопросы
Are F53 and F55 the same material?
Нет. Both are super duplex stainless steels, but F53 is UNS S32750 and F55 is UNS S32760. Purchase orders, MTCs and material traceability must show the exact required grade.
Can F55 replace F53?
Only with written engineering and project approval. A higher alloy designation does not by itself prove compatibility with the design code, процедура сварки, adjoining components or service environment.
Что должно включать в себя запрос предложения?
State F53/S32750 or F55/S32760, тип фланца, стандарт и издание, размер, сорт, лицом к лицу, график скважины или трубы, количество, тестирование, certification and inspection requirements.
Request a specification review and quotation
Send the complete RFQ or piping material specification. SASA FLANGE will review grade identity, размеры, лицом к лицу, inspection and documentation before production.
