Engineering materials

Technical notice and limitation of liability

The dimensions, thicknesses, finishes and other characteristics stated in this catalog are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASTM, ASME, ISO, NTC and EN, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.

Actual values may vary due to conditions inherent to the manufacturing process — dimensional and thickness tolerances, surface finish and residual stresses from rolling or forming — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: overloads, vibration, mechanical or thermal fatigue, corrosion and operating conditions different from those stated.

To know the certified behavior of a specific lot, TECTUL supplies the manufacturer's mill test certificate (MTC) upon request; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever structural integrity may compromise people or property; in such cases, consult our technical team first.
