Standard Test Method for Surface Finger Oxide Penetration Depth and Presence of Interparticle Oxide Networks in Powder Forged (P/F) Steel Parts
 N B797

Annotation

This test method covers a metallographic method for determining the maximum depth of surface finger-oxide penetration and the concentration of subsurface interparticle oxide networks in critical areas of powder forged steel parts.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
