Description
This 440F stainless steel reference material is a high-carbon, free-machining martensitic stainless alloy used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, OES). 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.
