Description
This 304 / 304L Stainless Steel Certified Reference Material (CRM) is designed for verifying the accuracy and performance of XRF analyzers, optical emission spectrometers (OES), and other elemental analysis instruments. Featuring a certified austenitic stainless steel composition, this reference material supports positive material identification (PMI), alloy verification, quality control, and laboratory testing.
Ideal for manufacturers, metal recyclers, inspection companies, and testing laboratories, this CRM provides a reliable reference for verifying stainless steel chemistry, checking instrument performance, and supporting material traceability requirements.
Common Applications
-
Handheld XRF Verification: Check analyzer performance using known concentrations of chromium (Cr), nickel (Ni), molybdenum (Mo), manganese (Mn), and other alloying elements.
-
Positive Material Identification (PMI): Support stainless steel grade verification during incoming material inspection, fabrication, and industrial maintenance.
-
Stainless Steel Sorting: Verify instrument response when distinguishing common stainless steel families, including 304/304L and molybdenum-bearing 316/316L.
-
Manufacturing QA/QC: Perform routine instrument verification to support consistent material identification and quality control procedures.
-
Laboratory Analysis: Use as a reference material for compatible XRF and optical emission spectroscopy methods.
