Metallurgical Testing Services

SHARE

Metallurgical testing is indispensable for the metal industry, facilitating the precise assessment of metal properties, complemented by chemical and mechanical testing. These services are crucial for evaluating the characteristics, integrity, and performance of metals, forming a core element of quality control and product development. Metal Power Laboratories (MPPL) offers an exhaustive suite of metallurgical testing services, which include metallographic analysis for grain size and microstructure analysis, as well as non-metallic inclusion assessment. The integrity of these tests is ensured through sophisticated, finely calibrated instruments and the proficiency of experienced metallurgists. Our microscope-based evaluation employs advanced optical and electron microscopes to scrutinize sub-surface structures, vital for identifying microstructural characteristics. Services provided include coating thickness, decarburization, carburization depth measurements, graphite nodularity analysis, and more, delivering reliable results and aiding manufacturers in achieving top-quality metal products.

Metallurgical testing plays a critical role in all metal industries, enabling the precise quantification of metallic properties alongside Chemical and/or Mechanical Testing. Metallurgical Testing is essential for determining the characteristics, integrity, and performance of metals, making it a vital part of quality control and product development processes.

At MPPL, our Metallurgical Testing Service offers comprehensive evaluations, including Metallographic analysis for grain size measurement, microstructure analysis, and non-metallic inclusion rating. The accuracy of these tests is driven not only by state-of-the-art, optimally calibrated instruments but also by the expertise and experience of our metallurgists.

Our Microscope-based testing methods utilize high-powered optical or electron microscopes to examine the sub-surface structures and fine details of materials. These techniques are critical for detecting material characteristics at a microstructural level. Sample preparation is vital, with care taken during sectioning and polishing, followed by acid etching to reveal the material's microstructure.

We offer a range of microscope-based testing services, including:

  • Coating thickness measurement by microscope: Accurate evaluation of coating layers to ensure protection and performance.
  • Decarburization depth measurement by microscope: Quantifying surface decarburization to assess the material's wear and fatigue resistance.
  • Carburization depth measurement by microscope: Measuring the depth of carburized layers for hardness and durability analysis. 
  • Graphite nodularity analysis: Ensuring proper nodularity in cast iron, a key indicator of mechanical properties.
  • Macro etch analysis:Examination of large-scale structural features to detect flow patterns and potential defects.
  • Grain Flow analysis: Assessing grain orientation, a crucial factor in determining mechanical strength.
  • Microstructure evaluation: Detailed analysis of material phases and microstructures, critical for performance prediction.
  • Weld evaluation: Inspection of welded joints for integrity, microstructure uniformity, and defect identification.
  • Near-surface examination : Detailed examination of the material's surface for detecting imperfections or deviations. Through a combination of cutting-edge technology and extensive technical expertise, MPPL’s Metallurgical Testing ensures reliable results and helps manufacturers maintain the highest levels of quality in their metal products.
