we have years of experience performing quality inspections on diverse stainless steels, from suppliers in China, India, and other regions. We follow a strict steel inspection checklist to detect both minor and major defects during our inspections. However, it’s important to note that the stainless steel inspection process can vary depending on the case. Here’s a glimpse into the parameters we generally consider when performing a stainless steel plate quality check.
The inspector will evaluate the products’ appearance at random using visual inspection, seeking any defects such as surface imperfections, scratches, or inconsistencies in finish. They also verify if there’s any identification information on the steel plates’ surface.
For example, in the scenario below our inspector noticed that there were scratches on the top of each tray and one stainless steel plate had deformations.

The inspector employs calipers or a ruler for physical dimension verification, comparing the dimensions against the specified requirements and tolerances. This quality check usually includes:
Measuring the plate’s thickness at various points.
Verifying the width and length dimensions against the specified values.

Another standard parameter is ensuring the stainless steel aligns with the specified requirements and industry standards. This verification is typically achieved by witnessing the factory’s chemical analysis. The inspector observes the entire process, from the sampling of the stainless steel material to the actual testing and analysis.
The analysis typically uses a spectrometer to determine the percentage of various elements present in the stainless steel material, such as chromium, nickel, molybdenum, among others.

Last but certainly not least, the inspector reviews the provided documentation, including the material test certificate, certifications and standards compliance, and other relevant documents.
Conclusion: Stainless Steel Plates Inspection
When purchasing stainless steel plates, it’s crucial to perform an inspection at the factory before receiving the goods. The stainless steel quality inspection can include visual inspections, quantity verification, dimension verification, document review, packing and labeling check, as well as witnessing a chemical analysis.
However, stainless steel plate quality control can be a challenge when the factory is located thousands of miles away. This is precisely where HQTS proves invaluable. With a footprint across more than 80 countries, we are well-equipped to facilitate steel inspections almost anywhere globally. Get in touch with us today for further information.
