Description
304L and 304H Austenitic Stainless Steel Certified Reference Material (CRM)
This 304L and 304H certified reference material is an austenitic stainless steel alloy widely used as a standard for calibrating and verifying your spectrometer (XRF, ICP-OES, Spark-OES, etc.). This material is precisely manufactured and certified to have traceable measurements and specified impurity levels, ensuring reliable results for laboratories 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.
