Super Dupleks F53 & F55 Flanges – UNS S32750 / S32760
Halaman perbandingan dan persediaan berdasarkan spesifikasi untuk dua tingkat flensa tempa super dupleks yang berbeda. It helps buyers identify the correct ASTM grade and UNS number before requesting manufacture.
Jawaban rekayasa cepat
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.

Grade and terminology check
| Procurement grade | ASTM A182 F53 | ASTM A182 F55 |

| penunjukan AS | S32750 | S32760 |
| Common EN number | 1.4410 | 1.4501 |
| Aturan seleksi | Use when the approved project specification calls for F53/S32750 | Use when the approved project specification calls for F55/S32760 |
Pemilihan bahan
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, suhu, 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.
Kontrol kualitas tersedia
- PMI and heat-number traceability
- Ferrite or phase-balance verification when ordered
- ASTM A923 or project corrosion testing when specified
- UT, PT and dimensional inspection to the ordered scope
Aplikasi yang umum
Aplikasi adalah isyarat seleksi, bukan persetujuan menyeluruh. Media proses, tekanan, suhu, data korosi, kelelahan, fabrication and code requirements govern final suitability.

Informasi yang diperlukan untuk kutipan
Berikan nilai materi, tipe flensa, standar dan edisi, NPS atau DN, kelas tekanan atau peringkat PN, jadwal pipa atau lubang yang tepat, menghadap dan menyelesaikan, kuantitas, tujuan pengiriman, perlakuan panas, mati suri, pengujian, sertifikasi dan persyaratan inspeksi pihak ketiga.
Pertanyaan yang sering diajukan
Are F53 and F55 the same material?
TIDAK. 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, prosedur pengelasan, adjoining components or service environment.
Apa yang harus disertakan dalam RFQ?
State F53/S32750 or F55/S32760, tipe flensa, standar dan edisi, ukuran, kelas, menghadap, jadwal lubang atau pipa, kuantitas, pengujian, persyaratan sertifikasi dan inspeksi.
