A practical incoming inspection checklist for stainless plate/coil:

1) Documents: mill certificate (EN 10204 3.1/3.2) matches the order; heat number, grade, standard, surface code and dimensions present; valid signature/date. 2) Marking and quantity: physical label heat number matches the certificate; coil/plate number, weight and piece count checked; packaging intact and dry. 3) Dimensions: thickness (multiple points, especially coil head/tail and both edges), width, length, inner diameter, coil weight; judge against the tolerance class. 4) Surface: visual inspection plus approved sample comparison; check scratches, roll marks, scale, rust spots, colour difference and edge cracks; blue-dot test for free iron if needed. 5) Verification: PMI spectrometry on the agreed sampling ratio (Cr/Ni/Mo matching the grade); mechanical or corrosion retests if required; retain samples and records. 6) Packaging and storage: protective film intact, moisture protection, lifting marks; store by grade/heat to avoid mixing.

Disposition and records:

• Accept: documents, dimensions, surface and verification all conform → stock. • Concession: minor surface/dimensional deviation assessed as fit for use → record and mark. • Reject: wrong grade, chemistry deviation, severe surface defects → isolate, photograph and raise a claim per the agreement.

Turn the checklist into a form and tick each item at every delivery — it substantially reduces mixed material and wrong-use risk.
