Metallurgical Testing



We have installed Olympus GX – 51 Metallurgical Microscope for micro examination. The GX – 51 inverted microscope provides stability to support excellent image clarity and superb resolution with high magnification. UIS2 optics delivers bright, sharp, high-resolution images suitable for all observation methods: bright field, dark field, differential interference contrast, polarization and fluorescence.

We provide following tests at our lab:

  •  Micro Structure Examination.
  •  Macro Examination.
  •  Grain Size Measurement.
  •  Nodularity.
  •  Phase Analysis.
  •  In-situ Metallography.


  •  Inter Granular Corrosion (IGC) Test as per ASTM A 262 Practice – A / B / C & E.
  •  Detecting Susceptibility to intergranular corrosion in Wrought, Nickel – Rich,Chromium – Bearing Alloys as per ASTM G 28.
  •  Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys as per ASTM G 48.
  •  Weld Decay Test as per ASTM A 249.
  •  Detecting Susceptibility to intergranular attack in Ferritic Stainless Steel as per ASTM A 763 Practice W / X / Y & Z.
  •  Evaluating Stress-Corrosion-Cracking Resistance of Metals and Alloys in a Boiling Magnesium Chloride Solution as per ASTM G 36.
  •  Ferroxyl Test as per ASTM A 380.
  •  Copper Sulphate Test as per ASTM A 380.


  • IN SITU METALLOGRAPHY In Situ Metallography procedures are performed “on location” or in the “field” on Components that are too large to bring to the metallographic laboratory. Generally, these components are still being used in service or must be returned to service and cannot be destructively sectioned or physically altered. Field metallography is also called in situ metallography, and it is sometimes called non-destructive Metallography. In situ metallographic work must br performed on-site without damaging the components. This means that portable metallographic instruments for grinding, polishing, and etching procedures are required.
