Evaluation of Non-Metallic Inclusions in Steel
Non-metallic inclusions can significantly influence the mechanical properties, fatigue life and overall performance of metallic components. Their size, shape, distribution and composition directly affect the strength and reliability of engineering materials.
At Om Metalab, we perform detailed inclusion rating analysis to assess steel cleanliness and material quality in accordance with internationally accepted testing standards.
Our metallurgical experts help manufacturers identify inclusion characteristics, verify process quality and ensure materials meet demanding industrial specifications.
