| Wear Severity |
Material contact and impact conditions |
Sliding abrasion, impact abrasion, or combined abrasion; operating temperature and moisture should be recorded. |
Review application drawings, material flow, impact points, and expected service hours before selecting a grade. |
Include the application profile in the purchase specification and technical approval record. |
High |
| Hardness Selection |
Nominal Brinell hardness |
Common abrasion-resistant plate categories include approximately 400, 450, and 500 HBW. Higher hardness can improve wear resistance but may reduce formability. |
Verify hardness at agreed test locations using a calibrated method and compare results with the applicable standard or purchase agreement. |
Require a heat number, test report, and traceability from plate to shipment documents. |
High |
| Chemical Composition |
Carbon equivalent and alloying elements |
Control carbon, manganese, chromium, nickel, molybdenum, boron, and other elements according to the selected grade and welding plan. |
Check the mill test certificate against the approved chemical limits. Use independent laboratory testing when risk or contract value justifies it. |
Ensure the certificate identifies heat number, product thickness, delivery condition, and applicable standard. |
High |
| Thickness and Flatness |
Dimensional tolerance |
Define nominal thickness, width, length, flatness, squareness, and edge condition before quotation. |
Measure thickness at multiple points away from plate edges and verify length, width, flatness, and visible edge defects. |
Pack plates with separators and moisture protection suitable for the transport route and storage period. |
High |
| Mechanical Performance |
Tensile and impact properties |
Specify yield strength, tensile strength, elongation, and impact toughness only when required by the application or governing standard. |
Review test temperature, specimen orientation, sampling frequency, and results on the material test certificate. |
Keep test reports linked to the shipment packing list and plate identification marks. |
Medium |
| Weldability |
Preheating and welding procedure requirements |
Confirm carbon equivalent, plate thickness, joint design, hydrogen control, heat input, and interpass temperature before fabrication. |
Approve a welding procedure and verify that consumables, preheat records, and welder qualifications meet the project requirements. |
Request cutting, forming, and welding guidance in the technical package rather than relying on informal instructions. |
High |
| Surface Condition |
Rust, scale, cracks, laminations, and repairs |
Surface must be free from unacceptable cracks, severe laminations, deep gouges, and contamination that could affect fabrication. |
Perform visual inspection under adequate lighting. Add ultrasonic testing for critical sections or when internal discontinuities present a significant risk. |
Photograph plate condition before loading and record any approved repair or deviation. |
High |
| Traceability |
Heat, plate, and batch identification |
Every plate or bundle should remain identifiable from production through cutting, inspection, packing, and installation. |
Cross-check markings, inspection reports, certificates, packing lists, and purchase order references. |
Use durable markings and provide a digital traceability register with shipment documents. |
High |
| Pre-Shipment Inspection |
Inspection timing and sampling plan |
Schedule inspection after production and before loading. Sampling level should reflect order value, criticality, and supplier history. |
Check quantity, dimensions, hardness, markings, surface condition, certificates, packaging, and nonconformities. |
Release shipment only after inspection findings are closed or formally accepted. |
High |
| Logistics Planning |
Manufacturing and transit lead time |
Allow time for technical clarification, production, inspection, export documentation, inland transport, ocean freight, customs, and inland delivery. |
Use a milestone schedule with agreed dates for drawing approval, production completion, inspection, loading, and document release. |
Confirm Incoterms, port handling, container or break-bulk suitability, cargo weight, and moisture-control requirements. |
High |
| Packaging |
Protection against corrosion and handling damage |
Use stable steel supports, separators, lifting points, and weather-resistant protection appropriate for the transport duration. |
Inspect bundle stability, protection coverage, lifting marks, weight labels, and condition of straps or securing points. |
Confirm package dimensions and gross weight for handling equipment, vessel planning, and customs documentation. |
Medium |
| Customs Documentation |
Commercial and technical document completeness |
Prepare commercial invoice, packing list, certificate of origin when required, material certificates, inspection report, and transport documents. |
Check consistency of product description, quantities, weights, heat numbers, tariff information, and consignee details. |
Send document drafts for review before loading to reduce customs or clearance delays. |
High |
| Supplier Support |
Technical response and corrective-action capability |
Define response times for technical questions, nonconformance notices, replacement requests, and urgent production support. |
Evaluate whether the supplier provides written root-cause analysis, corrective action, evidence, and prevention measures. |
Maintain a post-delivery support record covering claims, replacement lead time, fabrication guidance, and lessons learned. |
Medium |
| Incoming Inspection |
Receiving inspection at destination |
Inspect quantity, identification, dimensions, surface condition, packaging damage, and document consistency upon arrival. |
Quarantine damaged or unidentified material and issue a discrepancy report with photographs and measurement records. |
Record storage location, environmental conditions, and plate status before cutting or fabrication. |
High |
| Total Cost of Ownership |
Purchase, logistics, fabrication, and service-life cost |
Compare delivered cost with expected wear life, replacement frequency, downtime, welding effort, machining needs, and scrap risk. |
Review historical wear data and validate assumptions through pilot parts or controlled field monitoring where practical. |
Use performance feedback to update future grade, thickness, and supplier selection decisions. |
