Ferrite Content Measurement
TCR conducts the Ferrite Content Measurement in India by 2 separate methods. They are as under –
1) By Ferrite Meter – this is a digital method for checking ferrite content by Magnetic principle. This can be used for large castings where you can not cut samples for microscopic method and you need quick results. Please note that there is no ASTM specification for this method but it is quite popular and reliable and done very frequently all over the world.
2) Microscopic Method – this is done as per ASTM E 562 specification and we need a sample piece from coating to carryout this test.
