From PO to release
Quality Control for Stainless Steel Supply
Inspection begins with the written specification. Tests and documents are selected by product standard and purchase order, then linked to material identity before shipment.
01
Contract review
Grade, standard, product form, dimensions, tolerances, surface, edge or end, testing, marking, documents and packing are translated into the order file.
02
Source verification
The proposed mill or stock route is checked against material and product requirements before production or allocation.
03
Material identity
Heat and grade identification are reviewed. PMI can be included where required by the order or inspection plan.
04
Dimensional and visual inspection
Specified dimensions, tolerance points, surface condition, edge or end preparation, quantity and marking are checked using the applicable sampling plan.
05
Testing and documents
Ordered material certificates, mechanical or corrosion tests, NDT and third-party records are reviewed for consistency with the purchase order.
06
Release and packing
Nonconformities are resolved before release; bundle or coil identification is carried into export packing and shipment records.
Inspection options
- /EN 10204 inspection documents when ordered and supported by the supply route
- /Positive material identification (PMI)
- /Dimensional, visual and quantity reports
- /Hydrostatic, eddy-current, ultrasonic or other product-specific testing
- /Intergranular or pitting-corrosion tests for specified grades and services
- /Third-party inspection by an agreed independent agency
Who performs the tests
Heat chemistry, mechanical properties and ordered corrosion tests are performed and reported by the producing mill or qualified test laboratory for the selected supply route. Our release review checks the named standard, material identity, results and document references against the purchase order. Independent inspection can witness or verify agreed hold points when included in the order.
Product-specific NDT and pressure scope
Hydrostatic testing applies to ordered pipe or tube only when the product specification or purchase order requires it. Eddy-current or ultrasonic examination may apply to seamless or welded tubular products under the governing standard. Weld examination applies only to welded products, using the ordered method, sampling and acceptance criteria; these checks are not universal requirements for sheet, plate, bar or every fitting.
For company-level quality, environmental and occupational health and safety documents, review our management system certifications. These remain separate from shipment-specific inspection documents.
