Home

Met-Heat Engineers Pvt. Ltd. offers expertise on metallographic sample preparation and study of microstructure of various metals and alloys since 1990. Our qualified and trained metallurgists are experts for evaluation of various microstructures & confirming the heat treatment condition of material.

Our specialized on-site team is proficient in conducting in-situ metallography, including replica tests and non destructive microstructure examination using a portable in-situ metallography kit in accordance with ASTM E-1351 standards. Since 1990, we have been delivering these services to numerous esteemed clients to assess the deterioration of critical components in plants exposed to corrosive environments, high temperatures, and high pressure conditions.
