Full title and description

ASTM E45-18a — Standard Test Methods for Determining the Inclusion Content of Steel (Russian language edition). This publication is the Russian translation of ASTM E45-18a and provides the standard macroscopic and microscopic procedures used to evaluate and describe nonmetallic inclusions in wrought steels, including guidance on JK-type ratings, image analysis, and reporting conventions.

Abstract

This standard describes recognized procedures for determining the nonmetallic inclusion content of steel using four macroscopic methods (macroetch, fracture, step‑down, magnetic particle) and five microscopic systems (manual and automatic image analysis, JK and related ratings). The methods characterize inclusions by morphology, size, concentration and distribution and include guidance on specimen preparation, sampling, stereological measurement and reporting. The document does not set acceptance limits — those are agreed between purchaser and producer or specified in product specifications.

Scope

These test methods cover a set of macroscopic and microscopic procedures for rating and reporting nonmetallic inclusions in wrought steel. Macroscopic tests address larger inclusions visible at low magnification; microscopic tests assign inclusions to morphology-based categories (oxides, silicates, sulfides, complex inclusions, etc.) and may be performed manually or by automatic image analysis. The standard includes specimen preparation, sampling recommendations, stereological considerations, and guidance for steels modified with rare-earth or calcium treatments. It does not establish acceptance criteria — those must be specified elsewhere.

Key topics and requirements

• Four macroscopic methods: macroetch, fracture, step‑down, and magnetic‑particle examination.
• Five microscopic rating systems (including JK‑type ratings and SAM/visual systems) and procedures for automatic image analysis.
• Specimen preparation and microetching guidance to reveal inclusions and differentiate morphologically similar phases.
• Sampling and statistical considerations for lot assessment; importance of representative sampling and field counts.
• Stereological measurement guidance (volume/area fraction, counts per mm², spacing) and use of Practice E1245 for automated analysis.
• Reporting conventions: categories, sizes, severity ratings, and limitations (only surface‑exposed inclusions detected).
• Notes on special steels (rare‑earth or calcium‑treated) and practical guidance for distinguishing inclusion types.

Typical use and users

Used by metallurgical laboratories, quality control and inspection units, steel producers, forging and rolling shops, aerospace and automotive materials engineers, procurement and QA specialists, and research organizations. Common applications include heat/lot qualification, process control, materials acceptance testing, failure analysis and comparative studies of production routes or remelting practices.

Related standards

Standards commonly referenced or used alongside ASTM E45 include ISO 4967 (micrographic methods for inclusion content), ASTM E1245 (automatic image analysis practice), ASTM E407 (microetching practice), ASTM E1444 (magnetic particle testing practice) and AMS aircraft‑quality magnetic particle specifications (AMS 2300/2301/2303/2304). Other metallography and sampling practices (for example ASTM E3 and related ASTM metallography documents) are often used in conjunction.
