• Specifies maximum and minimum limits for elements including nickel, chromium, iron, manganese, carbon, silicon, copper, sulfur, aluminum, titanium, molybdenum, niobium, tantalum, phosphorus, nitrogen, boron, tungsten, and cobalt.
• Adherence to strict compositional limits ensures mechanical properties and corrosion resistance.

Mechanical Properties

• Minimum yield strength, tensile strength, and elongation values are defined for each alloy and condition.
• Mechanical tests are mandated for each production lot to verify compliance.

Heat Treatment

• Detailed requirements for final annealing temperatures dependent on alloy type to develop optimal grain size and mechanical characteristics.

Dimensional Tolerances

• Precise tolerances are established for outside and inside diameters, wall thickness, and length.
• Permissible variations depend on whether the product is cold-worked or hot-finished.

Testing & Inspection

• Hydrostatic or non-destructive electric (eddy-current) tests required for every pipe or tube to confirm structural integrity.
• Grain size, chemical, and mechanical property tests documented for each batch.

Product Certification & Traceability

• Requirements for documentation and possible third-party witnessing of tests and certifications.
