This test method covers the simultaneous determination of alloying and residual elements in low and medium carbon steel by hand held laser induced breakdown spectrometry (HHLIBS) for the following elements in the ranges indicated: Composition Range Mass % Element Applicable Range Quantitative Range Mass Fraction Range, Carbon x.xx to x.xx, Chromium x.xx to x.xx, Copper x.xx to x.xx, Manganese x.xx to x.xx, Molybdenum x.xx to x.xx, Nickel x.xx to x.xx, Silicon x.xx to x.xx and Vanadium x.xx to x.xx
This test method is suitable for identification of unknown metals found in existing construction, scrapyard and other situations. It also may be used for manufacturing control and for verifying that the product meets specifications. It provides rapid, multi-element determinations with sufficient accuracy to assure product quality. When so equipped, determination of carbon equivalency may be measured as an indicator of metal weldability and fitness for use.
The title and scope are in draft form and are under development within this ASTM Committee.
