Standards applied
Electrodes are controlled under YS/T 1312-2019 Molybdenum Electrodes for chemistry, density, dimensions and surface quality. Rods, plates and discs follow ASTM B387 / GB/T 17792 and ASTM B386 / GB/T 3876 respectively. Special shapes such as crucibles, stream mouths and needles are accepted against the agreed technical protocol.
Inspection reports and certificate copies
Each shipment includes a mill certificate and batch inspection record covering chemistry, density, hardness, dimensional tolerance, straightness and surface/internal defects. If you need management-system certificates, third-party test reports or a full batch record, state the purpose and format in your RFQ; our sales engineers provide redacted copies against the project. Certificate numbers are not published on the website so they cannot be misapplied to another batch.
- · Batch inspection report: supplied with each shipment and traceable by batch number
- · Mill certificate: grade, heat number, chemistry and dimensional results
- · Management-system and third-party reports: available per project against an RFQ or contract number
