Astm | A895 Verified

8–12 µm coating, resistant to methanol, acetonitrile, and 0.1% trifluoroacetic acid (pH 2). No thread galling.

While ASTM A895 materials are a machinist's dream, they do come with engineering compromises that must be considered:

Mandrel bend test (ASTM D522) over a ¼-inch (6.4 mm) mandrel – no cracking. astm a895

| Type | Description | Binder System | Typical Curing | |------|-------------|---------------|----------------| | Type I | Organic resin, air-dry or low-bake | Epoxy, epoxy-phenolic | 150–180°C, 20–30 min | | Type II | High-temperature bake (≥200°C) | Phenolic, polyimide, or fluorocarbon | 200–230°C, 15–20 min |
