321 Plates Had Documentation Gap — Resolved After Follow-Up
We ordered 321 hot rolled stainless steel plates, 15mm thickness, JIS G4304 standard, for heat exchanger fabrication. The plates themselves were dimensionally accurate and material composition tested correctly in our lab. However, the initial shipment was missing the required stabilization heat treatment records in the MTC documentation, which our quality system mandates. We flagged this to the supplier and the complete documentation was emailed within 48 hours. No material issues — purely a paperwork oversight. Project proceeded without further delay. I'd recommend they improve documentation completeness on first shipment, but their responsiveness in resolving it was good. Likely to reorder.
