Metallographic Testing Laboratory
Microstructure analysis to assess grain structure, inclusions, and material quality at a microscopic level.
What Is Metallographic Testing
Metallographic testing involves preparing, examining, and interpreting the structure of metals and alloys at a microscopic level. It reveals grain structure, phases, inclusions, and other microstructural features that directly affect material properties and performance.
Standards & Test Parameters
| Test Type | Standard | Metals Covered |

| Grain Size Estimation | ASTM E112 / IS 4748 | Carbon & alloy steels, copper alloys |
| Inclusion Rating | ASTM E45 Method A / IS 4163 | Carbon & low-alloy steels |
| Decarburization Depth | ASTM E1077 / IS 6396 | Heat-treated steel components, bars |
Frequently Asked Questions
What sample preparation is needed?
Samples require proper mounting, grinding, polishing, and chemical etching depending on the material and examination requirements. All preparation is handled in-house.
Can you analyze weld microstructures?
Yes, we perform macro and microstructural examinations of welds as per ASME Section IX and other welding standards to inspect heat-affected zones (HAZ) and fusion lines.
