Abstract

The accuracy and precision of spectrochemical analysis of metallic biocompatible grades, especially AISI 316 grades, should be superior to the routine ones because they must fulfill rigorous chemical composition specified by ISO 5832-1 standard. As it is known, the atomic emission spectrometry (AES) is the most used technique in instrumental elemental analysis of metallic materials due to its high ratio efficiency-cost. But, exactneess of AES spectrochemical analysis of 316L grades depend on some critical factors as: sample microstructure; nature, size and distribution of inclusions; inter elements interferences, sample preparation etc[1,2]. This is way the ISO 5832-1 doesn’t recommend AES for complete elemental analysis of 316L D and E alloy types..
