Corrosion Testing

complete range of corrosion testing as per Indian, ASTM, NACE, and other national and international standards.

Test Name : Corrosion Testing

About the test :

With growing awareness of the losses due to corrosion, estimation of corrosion resistance of a material is necessary.
ELCA has a team of dedic ated personnel including senior metallurgists with over 30 years of experience in related fields who perform and monitor the corrosion studies to carry out the tests with utmost perfection.
ELCA can carry out a num ber of corrosion tests based on Indian and International standards like :
