The NAS Quality Management System is designed to meet the requirements of ISO 9001:2015. NAS is registered through SRI Quality System Registrar to AS9100D at the mill and all NAS facilities are ISO 9001:2015 certified.
Laboratory facilities to meet the highest standards
To ensure the quality and integrity of our products, NAS’s laboratories conduct ISO 17025 certified testing using the latest technology and industry advancements. In addition to the surface quality of the steel, we also consider and evaluate other factors including the gauge, steel type chemistry, mechanical properties, finish and many other customer requirements.
Multiple samples are taken after each step of the melting process to test the chemistry in our Chemistry Laboratory and ensure proper compliance with customer specifications. Using an X-Ray Fluorescence (XRF) spectrometer and Optical Emission Spectrometer (OES) in a fully automated platform with LECO analyzers, we certify the chemical composition with a high degree of precision and accuracy, resulting in positive product identification and continuous traceability.
Additionally, our Mechanical Laboratory utilizes an automated tensile testing system to deliver both consistent and repeatable results. This automated system eliminates any possible testing bias, measurement error, or recording errors by incorporating a gauging station, hardness tester, bar code scanner, and direct result upload capability.
NAS’s products are held to our high quality standards by our trained inspectors at several different points in the process. Inspectors ensure accurate measurements are taken of the steel, as well as examine the surface quality and report any defects on the material. To aid our inspectors in defect detection, we have multiple in line automatic inspection systems throughout our processes that visually analyze for any surface abnormalities. This helps us ensure that we pass a quality product onto our customers.
