Overview

ISO 9328-2:2018 - "Steel flat products for pressure purposes - Technical delivery conditions - Part 2" defines the technical delivery conditions for plates and strip used in pressure equipment made from non‑alloy and alloy steels with specified elevated temperature properties. It complements ISO 9328-1 (general requirements) and provides grade‑specific chemical, mechanical and delivery‑condition requirements (see Annexes A and B).

Key topics and technical requirements

Scope and applicability: Applies to plates and strip for pressure equipment; steel grades and limits are listed in Tables A.1 and B.1. Definitions and general requirements of ISO 9328‑1 apply.

Classification & designation: Differentiates non‑alloy grades (e.g., P235GH, P265GH, P295GH, P355GH, PT410GH, PT450GH) from alloyed special steels, with designation rules per ISO 9328‑1.

Delivery conditions: Default and optional delivery conditions include normalized (+N), normalized and tempered (+NT), quenched & tempered (+QT) and untreated (+AR). Normalizing rolling and simulated heat‑treatment tests are covered.

Chemical composition & product analysis: Requirements per cast (heat) analysis in Tables A.1/B.1, with permitted product analysis deviations.

Mechanical properties & testing: Tensile, yield and impact requirements at ambient and elevated temperatures; options for mid‑thickness test pieces and impact energy values.

Special tests & integrity checks: Hydrogen‑induced cracking (Annex G), step‑cooling (Annex H), weldability requirements, resistance to hydrogen‑induced cracking and embrittlement of CrMo steels.

Inspection, sampling & marking: Types of inspection documents (inspection certificate 3.1 per ISO 10474 is an example), sampling plans, retests, sorting and marking rules.

Informative annexes: Cross‑references to EN/ASTM/ASME/JIS equivalents (Annex C), heat‑treatment guidelines (Annex D), time‑temperature parameters and creep reference data (Annexes E and F).

Practical applications and who uses it

ISO 9328-2 is intended for:

Steel producers and mills supplying plates and strip for pressure vessels, boilers, heat exchangers and piping where elevated temperature performance is required.

Fabricators and welders specifying delivery conditions and verifying material suitability after heat treatment.

Procurement and quality managers establishing technical delivery conditions in purchase orders.

Inspectors, testing laboratories and certification bodies performing compositional and mechanical testing, HIC and step‑cooling evaluations.

Design engineers referencing material properties for high‑temperature pressure equipment compliance.
