ASTM B564 UNS N06625 Flanşlar: Seviye 1 vs Sınıf 2
Hızlı cevap: ASTM B564 nikel alaşımlı dövmeleri kapsar, içermek UNS N06625 flanşlar, but it recognizes two heat-treatment conditions. Seviye 1 is annealed and is normally employed up to 1100°F (593°C). Seviye 2 is solution annealed and is normally employed above 1100°F where resistance to creep and rupture is required. These are specification conditions—not universal design limits. The purchase order must also define the flange standard, boyut, sınıf, karşı karşıya, bore and testing.

Buyers often write only “ASTM B564 UNS N06625 flange.” That identifies the material route, but it does not fully define the required item. Seviye 1 versus Grade 2 affects heat-treatment condition and intended temperature regime, sırasında ASME B16.5 or another dimensional standard controls a different part of the order.
Ne ASTM B564 Covers
ASTM B564 is a material specification for nickel-alloy forgings. İçin UNS N06625, it sets requirements associated with chemistry, ısıl işlem, mechanical properties and testing. It does not, by itself, define every flange dimension or pressure-temperature rating.
Keep the standards separate: ASTM B564 answers “what forged material and condition?” A dimensional standard such as ASME B16.5 answers “what flange dimensions, toleranslar, marking and pressure-temperature framework?” The project specification and purchase order connect both.
ASTM B564 Seviye 1 vs Sınıf 2
| Kontrol etmek | Seviye 1 | Seviye 2 |
|---|---|---|
| Durum | Tavlanmış | Solution annealed |
| ASTM service note | Normally employed up to 1100°F (593°C) | Normally employed above 1100°F (593°C) where creep and rupture resistance are required |
| Buyer action | Eyalet Notu 1 and verify the required condition on the MTC | Eyalet Notu 2 and verify the solution-annealed condition and project requirements |
| Oyuncu değişikliği | Do not substitute one grade for the other without engineering and purchasing approval. | |
The 1100°F boundary is not permission to select a flange from temperature alone. Tasarım baskısı, applicable code rules, korozyon ortamı, fabrication history, mating components and project-specific acceptance criteria still need review. Hot working or subsequent reannealing can also affect properties, so the delivered condition and traceability matter.
ASTM B564 vs ASME B16.5
ASTM B564 Ve ASME B16.5 are complementary, not competing specifications. A usable order may identify ASTM B564 UNS N06625 Seviye 1 veya Sınıf 2 for the forged material, Daha sonra ASME B16.5 for the applicable flange size, sınıf, boyutlar, toleranslar, marking and testing framework.
“Alaşım 625 flange” is therefore incomplete. Buyers should add flange type, NPS veya DN, sınıf veya PN, karşı karşıya, delik veya eşleşen boru programı, boyutsal standart ve baskı. Pressure class is not a material grade, ve Sınıf 1 veya Sınıf 2 is not a pressure rating.
What to Check on the MTC
The MTC should be checked against the purchase order and the adopted specification edition. En azından, review:
- Malzeme kimliği: ASTM B564, UNS N06625 and the ordered Grade 1 veya Sınıf 2 durum.
- İzlenebilirlik: heat or lot reference connected to the flange marking and item documentation.
- Isıl işlem: the reported condition and any required temperature record or statement.
- Chemistry and mechanical results: actual reported values assessed against the governing edition and purchase order.
- Required tests: only the examinations, supplementary requirements and acceptance criteria actually invoked by the order.
- Certification scope: document type, manufacturer identity, inspector or third-party endorsement when contractually required.
Producer datasheets are useful for typical alloy behaviour, but typical values are not acceptance limits for a purchase order. Acceptance should follow the cited material specification, dimensional standard and project requirements.

Sıkça Sorulan Sorular
öyle mi ASTM B564 the same as Inconel 625?
HAYIR. ASTM B564 is a product/material specification. UNS N06625 is the alloy designation commonly associated with Alloy 625; Inconel is a trademark. A controlled order should cite the applicable specification, UNS numarası, grade or condition and product details.
Yapmak ASTM B564 define flange pressure class?
HAYIR. Seviye 1 ve Sınıf 2 describe material conditions. Pressure class belongs to the applicable flange standard and must be evaluated with temperature, material grouping and code requirements.
Not Verebilir 2 replace Grade 1?
Otomatik olarak değil. Even if Grade 2 is solution annealed, substitution can affect the approved specification, design review, documentation and commercial scope. Obtain formal approval first.
Which standard applies to Alloy 625 flanşlar?
ASTM B564 yaygın olarak kullanılır UNS N06625 forged flange material. The flange also needs an applicable dimensional standard such as ASME B16.5, or another project-specified standard for its size and type.
