The acceptance path covered in this guide comes down to four linked checks: confirm the EN 10204 3.1 certificate is correctly issued and signed; verify chemistry against PO\/spec with the right method (PMI for screening, OES\/ICP for carbon-critical decisions); map hardness at head\/mid\/tail \u00d7 edge\/center\/edge and interpret the spread, not just the average; and verify decarburization depth when the application is edge-sensitive.<\/p><p>Traceability is what ties these checks together. If you can connect the MTC heat number to the coil tag, to your receiving log, and through to internal lot numbers after slitting or grinding\u2014you have a defensible QA record. If any link in that chain is missing, you have paperwork, not traceability. Re-verify hardness and surface condition after any secondary process (slitting, grinding, heat treatment) that changes the working surface or splits the lot identity.<\/p><p>Consistent results require consistent identity. That&#8217;s the same internal discipline we apply at&nbsp;<strong>Maxtor Metal&nbsp;<\/strong>when aligning documentation and verification steps between supplier and buyer.<\/p><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><h3 class=\"wp-block-heading\" id=\"b9411014-6743-4876-b0e0-d8f88a33a9d9\">Author Bio<\/h3><p><strong>Jesse Xu<\/strong><br><em>Senior Quality Engineer | Maxtor Metal (QA Department)<\/em><\/p><p>Jesse Xu is a Senior Quality Engineer at Maxtor Metal with over 15 years of hands-on experience in tool steel metallurgical quality assurance, material inspection, and failure analysis.
