Austenitic, Duplex, Super-duplex stainless steels require adequate proportion of ferrite in the product to obtain acceptable corrosion resistance and strength and especially resistance to Stress Corrosion Cracking  (SCC). The laboratory based destructive method such as microstructural analysis on the test specimen or sample obtained from the batch of the product or components provides statistical quality assurance.

In order to guarantee the acceptable ferrite content in the final product, ferrite measurements are performed on the actual product using Fisher ferritoscope MP30C. Ferrite measurement using Fisher Ferritoscope is a non-destructive test method which assures the quality of the product without the need of expensive laboratory based destructive test methods. The test is performed in accordance with the manufacturer's instructions, EXXON Mobil, ESSO Shell specification and laboratory based validated methods. Experienced Metallurgist, Engineers and Technologist at LMATS provides accurate and reliable ferrite measurement on-site and in-situ products.
The Inclusion Contents test cover a number of recognized procedures for determining the nonmetallic inclusion content of wrought steel. Macroscopic methods include macroetch, fracture, step-down, and magnetic particle tests. Microscopic methods include five generally accepted systems of examination. In these microscopic methods, inclusions are assigned to a category based on similarities in morphology, and not necessarily on their chemical identity.

Metallographic techniques that allow simple differentiation between morphologically similar inclusions are briefly discussed. While the methods are primarily intended for rating inclusions, constituents such as carbides, nitrides, carbonitrides, borides, and intermetallic phases may be rated using some of the microscopic methods.

LMATS is NATA accredited to perform inclusion contents analysis in accordance with AS 2087 – macro test method and AS 2197 – micro test method.

Grain Size Measurement covers the measurement of average grain size and include the comparison procedure, the planimetric (or Jeffries) procedure, and the intercept procedures. These test methods may also be applied to nonmetallic materials with structures having appearances similar to those of the metallic structures shown in the comparison charts. These test methods apply chiefly to single phase grain structures but they can be applied to determine the average size of a particular type of grain structure in a multiphase or multiconstituent specimen.

LMATS is NATA accredited to perform grain size analysis in accordance with AS 1733 and ASTM E112.

The comparison of observed graphite particles with the structures shown in the charts give only purely descriptive information on the type, distribution, and size of the graphite in the sample being evaluated. It does not indicate except in a very broad way the origin of the graphite, or the suitability of the iron-carbon alloy for a particular service.

The Graphite Classification Test method covers the classification of graphite in cast irons in terms of type, distribution, and size. This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray irons, malleable irons, and the ductile (nodular) irons

LMATS is NATA accredited to perform graphite classification in accordance with AS 5049 and ISO 945.

This test method is used to designate graphite microstructure in cast irons.
