1.1This guide covers the description of carbide structures in annealed high carbon bearing steels.
1.2Included is a guide for rating steel specimens by a graded series of photomicrographs showing the incidence of certain conditions.
1.3The reference photomicrographs are graded illustrations of annealed carbides categorized by size, network, and lamellar content (shape).
1.4This guide is to facilitate communication and description of microstructure. It does not establish limits of acceptability. Such limits are a matter of agreement between user and producer.
1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use.
