PMI is a nondestructive means of determining the chemical composition of metals.

​

The most common, portable, and easy-to-use PMI tool is a handheld XRF(X-ray fluorescence) analyser. These instruments are highly accurate at determining the chemical composition of alloys, and thereby their grade. Moreover, they do so within a matter of 5 seconds or less for most stainless-steel grades, without significant sample preparation, and safely

​

customers request PMI service when:

• a sample cannot be cut for testing

• a mixed lot is suspected

• material identification/documentation has been misplaced
