Certified reference material for 410 stainless steel (UNS S41000), intended for XRF and spark OES calibration, verification, and quality control.

The 410 Stainless Steel CRM is designed for XRF and spark optical emission spectroscopy (OES) applications where verification of martensitic stainless steel chemistry is required.

This material supports accurate measurement of key elements such as chromium, carbon, manganese, nickel, and other minor and trace elements commonly used to confirm 410 stainless steel composition. It is suitable for routine analyzer checks, method validation, and ongoing QA/QC in both handheld and laboratory environments.

The CRM is supplied as a solid metallic disc, providing a stable and repeatable surface for XRF and OES analysis.

Frequently Asked Questions

What is this reference material used for?
This CRM is used for calibration, verification, and quality control of XRF and spark OES analyzers when analyzing 410 stainless steel.

Is this suitable for handheld XRF analyzers?
Yes. Chromium and other major alloying elements in 410 stainless steel are well suited for verification using both PIN and SDD handheld XRF analyzers.

Can this be used for spark OES?
Yes. The solid disc form and certified homogeneity make it suitable for spark OES calibration and performance checks.

Does this include carbon content?
Yes. Carbon is included to represent full alloy chemistry, but it is not measurable by handheld XRF and is primarily relevant for OES users.

Is this supplied as chips or solid form?
This CRM is supplied only as a solid disc for repeatable XRF and OES analysis.
