ASTM B887-26 — Cemented Carbide Coercivity Testing
Procurement reference for non-destructive coercive field strength (Hc) measurement of cemented-carbide products.
Edition control: ASTM B887-26 is listed as active by ASTM; checked on . This original MNK-G.S.A summary does not reproduce or replace the protected ASTM publication. Confirm the current authorised edition and governing order documents before use.
Scope in Procurement
ASTM B887-26 covers coercive field strength (Hc) measurement of cemented-carbide materials and products using coercive-force instrumentation. SI units govern, with an exception for the industry-used oersted (Oe).
For a controlled grade family, coercivity can support relative comparison of carbide grain size, binder content and possible carbon deficiency and can flag deviation from a specified norm.
The result is an indirect estimate rather than a complete chemical or metallographic description. Composition, magnetic binder behaviour, calibration and grade-specific correlation must be documented.
| Property | Coercive field strength (Hc) |
| Material context | Cemented-carbide materials and products |
| Procurement role | Non-destructive comparative process and grade control |
| Scope boundary | Does not replace chemistry or direct metallographic grain-size measurement |
