Description
Certified Reference Material for 1005 Carbon Steel
This 1005 carbon steel certified reference material is a low-carbon steel alloy widely used as a standard for calibrating and verifying your spectrometer (Handheld XRF, Handheld LIBS, Benchtop XRF, OES, etc.). This material provides a known composition for confirming your instrument's grade identification accuracy, supporting laboratories and field operations performing calibration, quality control, and materials testing.
For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
