ISO 9328-3:2018 specifies the requirements for flat products for pressure equipment made of weldable fine grain steels as specified in Tables A.1 and B.1. The requirements and definitions of ISO 9328‑1 also apply to this document. NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with ISO 643. NOTE 2 This document offers the possibility to specifying products in accordance with European design codes and ASME-type design codes.

Overview

ISO 9328-3:2018 - "Steel flat products for pressure purposes - Technical delivery conditions - Part 3: Weldable fine grain steels, normalized" specifies the technical delivery requirements for flat steel products intended for pressure equipment. It covers weldable fine grain steels (ferritic grain size 6 or finer per ISO 643) and applies together with the general requirements of ISO 9328-1. The standard supports ordering and supply in accordance with both European design codes and ASME-type design codes (see Annexes A and B).

Key topics and requirements

Scope and classification: Defines steel grades and qualities (room temperature, elevated temperature, low temperature, special low temperature) and their designation rules referencing ISO 9328-1.

Delivery condition: Default supply is normalized; untreated (+AR) delivery or simulated normalized tests are possible if agreed at order.

Chemical composition: Cast (heat) analysis limits are in Tables A.1 and B.1; permissible deviations for product analysis are specified (Table 1). Option to agree carbon-equivalent limits.

Mechanical properties and testing: Requirements for tensile and impact properties, including options for mid-thickness samples, longitudinal test piece verification, and elevated-temperature R values (Tables A.3–A.5, B.3–B.4).

Weldability and HIC: Provisions for weldability statements and optional hydrogen‑induced cracking (HIC) evaluation (Annex D).

Inspection and documentation: Specifies inspection types, sampling, marking and inspection certificates (example: Inspection certificate 3.1 per ISO 10474).

Dimensions and tolerances, internal soundness, surface condition: Delivery requirements for manufacturing and quality control.

Normative references: Key referenced standards include ISO 9328-1, ISO 643 (grain size), ISO 4948, ISO 10474 and EN/ASME-related guidance.

Practical applications and users

ISO 9328-3 is used where reliable, weldable flat steel products are required for pressure equipment and vessels. Typical users:

Steel producers and plate mills specifying chemical and mechanical delivery requirements

Pressure vessel and boiler manufacturers selecting plate material for welding and fabrication

Fabricators and welders assessing weldability and normalized condition suitability

Design engineers working to European or ASME-type pressure codes

Inspection and certification bodies issuing inspection certificates and verifying compliance

Procurement specialists placing orders for steel plates used in oil & gas, petrochemical, power generation and pressure-retaining components
